As a professional race car driver NASCAR breaks are just as critical as acceleration on a paved short track .

So in summary larger rotors and calipers can help shed off heat which will help delay or even prevent brake fade under extreme use such as a race track, but they do not decrease stopping distance. Also a video on master cylinder ratios would be nice.

Size matters for braking the disc itself, it's a question of leverage, but it's useless as brake power is always higher than the tyre ability to brake. So your car would skid anyway once you overpowered the tyres ability to stop the car. If you have ABS, it'll make no difference. I don't think he mentions that because it would need further explanation. So technically the disc stops better if it's bigger, it wouldn't give any advantage in stopping the car. That's why cars or motorcycles have different brakes at the front and at the rear, they're all calibrated according to weight distribution, tyres, suspensions, etc.. ABS interrupts and reactivates the brakes not to have you car skid, that means brakes are already too powerful, no point in making them more powerful. In racing condition is different, standard brakes are not calibrated to constantly be under pressure, therefore you need something that keeps them at the optimal temperature even if you brake hard all the the time. Whether you do that with bigger brakes or better ventilation, that depends on many factors. E.G.: on motorbikes the front is quite big and has holes for better cooling, on cars the front one can't go beyond a certain size, so it normally has two parts stuck together that lets air flow in between these two parts for cooling purposes.

Many years ago, I was told that THE best performance upgrade you could buy for cars or bikes was fuel, or to put it another way more time behind the wheel, or if you really need it breaking down, improving the driver. A better driver won't use the brakes as often or as much, without sacrificing speed, because they understand the capabilities of their chosen ride. Excellent video as always ... 🙂

@johnsantiago7836 is 100% correct. If your brakes are sufficient to lock up your tires (or engage the anti-lock) then the limiting factor is your tires. All the rest is about heat management. Another unpopular but true thing about brakes... drilled and slotted rotors are a marketing gimmick. With old pads that off-gassed a lot when they overheated drilled and/or slotted rotors helped but they are good for nothing except marketing today.

@JellyBean-ed2uq

​@@ukemike1well I had the same opinion, but upon further inspection, it is not the case. Drilled or slotted disks can and will improve braking distance on HARD breaking, just because they self clean better and they gain a tiny cross sectional area that helps them cool a bit faster (not by a lot of course, and this isn't the main reason as to why they are "better" than non drilled ones). You can see an experiment garage 54 did, but we also did some simulations in my engineering school, and yes, just because they can clean themselves better, the callipers can grab the rotors more efficiently without slipping. The gains while kinda small, they are noticeable. Are they worth the extra 80-xxx$ more than the regular ones? Absolutely not, and THAT makes them a marketing gimmick. Do they have some benefits tho? Yes

Brilliant video! Spot on! I’ve been an Automotive Engineer for the past 14years, most of that time being in Brakes Engineering, working for Renault, Ricardo UK, Bosch Engineering and recently I moved to Jaguar Land Rover and I can confirm that ‘bigger’ brakes will only do one think, in the vast majority of cases, they will disturb the brake feel and the modulation as the brakes will tend to lockup faster as you very well stated in this video. Also if they are aftermarket brakes don’t be surprised if they are ‘noisy’. Unless you are racing, I wouldn’t even touch the stock brakes. We spend years getting the system sized correctly and the adequate pedal feel. More importantly most of the stock brakes are quiet, because of a very good reason we literally spend over two years in Brakes Refinement testing by making sure that the brakes are quiet, many millions of pounds are spent in that respect. With aftermarket brakes you cannot have the same level of Brakes Refinement as the aftermarket doesn’t have access to the same level of dyno, CAE and vehicle testing as an OEM does. Most of the braking systems are oversized anyway, as most OEMs design the braking system around the AMS test, which is not even a legislative requirement. The AMS test is extremely severe (10 consecutive brake stops from 100kph to 0) and it’s not a realistic use case. Consequently we end up with very big brakes and more importantly very heavy brakes. Therefore do yourself a favour and unless you are racing and you need the thermal capacity, then do not waste your money on shinny new ‘big’ brakes.

I don't think AMS test is extremely severe. Imagine going down a mountain road. You might keep the brakes engaged for a lot of the trip going down. Would really suck if the brakes start to fade. Also imagine the brakes aren't brand new, but on a 20 year old car, that was maintained by an average person, and that doesn't really care about fanatic maintenance. Most people do maintenance on brakes only when weird sound appear, especially on older cars.

Personal experience, If you only do the open air intake without heat shielding you will lose power. If you make it into a cold air intake with heat shielding, you’ll probably still lose power. If you have a turbo or compressor which you have upgraded, then an cold air intake will work. Noticed it myself when the stock new intake was sucked into the box after upgrading a supercharged mini r53 and the car needed a lot more air. In my mind it gave it a bit more torque and made it faster. Never did real tests though but the sucked in airfilter was for me a give away that it’s better to upgrade after putting a lot more horsepower into a car.

I bought a car with Brembos fitted from new, the sort of things people upgrade to. I managed to cook them on the track to the point of having no braking no matter how hard I pushed. Not just brake grade, but brake vanish!! Came home, threw out the rotors and pads and upgraded those. Same brakes, same fluid, but better heat dissipation from the rotor and oars that were more heat tolerant and I now have a car that feels no different to drive, but the more I brake, the better it stops as heat gets into the system. So upgrading the right components, not the whole braking system, is where you’ll get the most benefit. Great video once again, love your stuff!

My previous car I added a brake kit purely because after a few track sessions I'd have issues with the sliders. Even after rebuilding the calipers, this wasn't the issue with fixed multi pot calipers. I actually got to try the car with the same brake compound in good condition with and without big brakes. I definitely wasn't able to do as many laps before fade but pedal feel was better on the standard setup again like D4A said it messes up the MC ratio somewhat. With the BBK fitted the pedal was definitely slightly mushier, not terribly but enough for you to notice. The fix for it was to switch to a different MC, but while it was worse than the standard setup it wasn't outright dangerous. Funnily enough on the trackday with the standard calipers a lot of people left in the afternoon and the track was very quiet. This meant me doing way more laps than I normally would and out of all the braking components it was the fluid that went first as I had a long session and all of a sudden I went to brake and the pedal pretty much went to the floor. The car still did slow down enough so I let everything cool down and came in. Turns out I'd boiled the fluid (Fresh ATE Superblue when you could still get it) before I'd reached the limits of the pads/discs/calipers. One other benefit was a reduction in unsprung mass that actually improved general feel on the front end as the 4pot wilwoods were much lighter than the standard cast iron slider calipers. Stopping distance however was identical, on track the only thing that noticeably improved braking distances for me was going from a regular summer tyre to an actual track tyre. My current car has a factory Brembo option which I'm going to be fitting instead of an aftermarket kit, it's definitely worse on the unsprung mass side but there won't be any brake bias or MC issues. I may not need this but to be honest after you've had any sort of loss of braking during track driving I'd rather have more safety margin than not.

You don't need to upgrade to ride on the streets, that's the point. On track of course you need better heat dissipation, as you're constantly breaking to almost locking, and generating tons of heat in the way. But in the street, unless you're a public danger, you don't need bigger brakes. However, more leverage can lead to a better braking sensation so if that's your objetive, do it. If you just want to brake more, put on wider tires, as i've made in my car, which will also make your car steer better.

This is a great video! I've had this conversation with so many people. Tires are more important to stopping than brakes, especially on a sports car. I only upgraded my brakes on my RX-7 once I improved my driving skills to surpass what my tire/brake set-up could handle. I upped the tires to a track tire, and then upgraded the brakes to match the upped grip. I didn't go BBK though, I only upgraded pads and discs to slotted.

Towards the end I can definitely say that the single best performance part I've ever bought for a car were lighter wheels. Lower unsprung weight dramatically improves handling and lower rotating mass has an exponential effect on acceleration and braking at higher speeds. At legal speeds though it doesn't make much difference.

Tires and then suspension are generally going to be your biggest inprovements to braking time. Once youve improved the tires though, you add more traction, and thus it CAN help to improve the brakes (more pistons or more leverage or both). It CAN help. It probably wont in many cases, but hell, it wont generally hurt much of anything to my recollection, and a lot of the better quality brake kits, and pads, and such have better brake fade characteristics under heated conditions. (See also racing) Another thing you should take into account, if you throw on 20s or something ridiculous onto your small car youre adding a lot of extra rotational energy to those tires, and thus it is often worth it to throw in better brakes to handle it.

I've learned more amazing facts about engines and cars from this Man in the last 3-4 years than basic to sophisticated knowledge since I was in my teens. Things that, as an engineering physicist, I should have known. Or figured out on my own. But "motorhead lore" and what seemed to be complicated but "common sense" had polluted my mind. If he says something about motor vehicles, I believe him. And then go back and figure out why I've looked at it wrong for decades. As an aside. I drove big heavy American V-8s from my teens (1974 -1987). Many were used and cheaper models and had front disk brakes and rear drum brakes. Although I started with a disc/disc 1953 Ford Flathead. I don't know if differential brake wear caused me a problem. I lived and went to school in LA for 4 years (1980-1984). To numerous to count times, I would come to partially blind freeway corner at ~65 mph only to see traffic at a dead stop ahead. I would stomp the brakes in my 350 V-8 1973 Monte Carlo. The rear drums would immediately lock up. But not the front discs. The car would end up, what seemed like, 80 degrees sideways with me steering into the turn. Totally in control directionally. Lots of screeching. I could, literally, control the sideways angle of the car by modulating brake pressure. I'd keep it sideways, in total steering control until I was pretty certain I would stop and gradually let off on the brakes. First slowly, and then immediately, it would snap back to straight forward. I was never trained at all in this type of driving. I just happened a lot in LA back then. The horrors of the 55 mph days. Going 55 mph on a LA freeway would get you killed. Many of you trained drivers are probably saying, duh? It happened often enough and was so amazing to me that I developed skills in using that technique. My previous cars were also heavy only with drum/drum brakes. This never happened with them. Obviously before ABS systems, did this mean that the proportioning valve was not correct or out of adjustment? Could I have corrected it to make rear lockup less likely? My personal observation is that a front heavy V-8 car stopped faster when controllably traveling sideways? Am I incorrect about this? I've always been leery of front disc/rear drum brake cars since then. Comments and thoughts are welcome. After that, I bought a used 1973 350 Corvette Convertible with front and rear discs plus 4 wheel independant suspension. Life was Grand. When I was 25 years old. Just Graduated Med School. I learned what a "women magnet" car really was. It was "chick magnet" back then. But I didn't want to offend any Karen's who police KZread for micro aggressions. Only one more personal anecdote and a question. I promise. From 1982-1986, I also occasionally drove my girlfriends early 80s Toyota Tercel 4 cylinder low power and light weight 4 door. Narrow skinny tires on ~14" or less, steel rims. All factory parts. Not a "hotrod" car or one that inspired spirited driving ever. That car spun itself ( my interpretation) or I spun it >360 degrees on ~ 5 occasions. Always at normal driving speed. Every time, the road was coated with a wet watery mist on top of a normaly dry oily road surface. Never touched the brakes until it was out of control. I guess this is why F1 drivers get the Big Bucks? My first front wheel drive car, I realized that just letting off the throttle in a normal speed wide sweeping turn simulated only putting on the front brakes. The opposite of a RWD car. Instantly Initiating the out of control spin. I was lucky as no other traffic was ever around. An instant lesson in oversteer. I believe it was a dangerous vehicle. I've driven many later 1980s FWD cars without any problems. Any ideas on what was done to rectify this vehicle based design problem? Before ABS, traction control, etc.?

what you want to do is dissapate heat from repeated high speed braking. So things that manage heat better are brake pad compound, rotors with higher vent count (maybe a bit thicker as well), brake ducting, high quality high temp brake fluid. Now to take advantage of ur clamping force you need more traction, I.e a well setup suspension and proper tires.

It's pretty obvious, really. The forward weight transfer while braking means that the front tires have more traction and can take more braking force. The master cylinder applies more hydraulic force to the front. If all wheels got the same, the rear wheels would lock up (bad) while the fronts are not yet achieving maximum braking potential.

Big brake kits will typically improve your brake feel and ability to modulate the brakes. People confuse this with "better" or "stronger" brakes. Like you said, the tire stops the car, not the brakes. Stock brakes have enough grip to lock up the tires. That is all the brake you need. Anything beyond that is all about brake feel, or ability to dissipate heat for repeated high speed stops (like track use).

This was suggested to me again for some reason. Once you modify the car from stock to make it faster with more grip it is possible to overwhelm the stock braking system where it will fade before you have thrown off all of the speed. For instance a giant truck where someone goes from 26" tires to 44" tires there may not be enough mass in the stock brakes to not fade in a panic stop from 120kph to 0kph.

Firstly, thank you for the wonderful refresher of the technology I learnt at college, nearly 50 years ago. Right from the start I was thinking 'heat dissipation' and tyres' grip. The original 'classic' Mini had drum brakes, always capable of stopping the wheels turning if properly maintained. The upgrade to discs (from the Cooper versions) was unnecessary unless used for competition. The later fitment of discs by Rover was to remove the need for adjustment of the drums every 3000 miles, not for any additional braking effort. I must however take you to task. The most important feature of any car in amking it safer, is the driver. Sadly, that is the most difficult part to improve, so we go with ABS, EBA, etc.

@@vaerxxx3231 Yes there is weight transfer under braking but how much weight transfer is dependent on some vehicle physical attributes (such as the height of the CoG above the ground, weight distribution etc) but crucially weight transfer is also dependent on the rate of deceleration. Higher rate of decel will result in more weight transfer. And now it gets tricky because there are countless factors that can effect grip and thus peak deceleration (tyres, wet/dry road, weight etc). So in reality it is impossible for any passive brake system to achieve an optimum brake bias for all conditions. The result is vehicle manufacturers tend to opt for a 'safe' brake bias (i.e. forwards bias) because as you say, a overly rearwards bias would be like pulling up the handbrake every time you brake hard and that is definitely NOT the way to make a car fast.... However, since all manufacturers go for a very 'safe' brake balance, there is often performance to be found by shifting the brake bias marginally rearwards (e.g. by installing rear pads that have a slightly higher friction coefficient than the front pads). This will shift the brake bias rearwards towards a more 'neutral' brake balance which will reduce stopping distances. The tradeoff being the rear of the car will become slightly more unstable during braking.... A 5-10% shift REARWARDS in brake bias however is still very controllable for even a moderately skilled driver and could even further improve lap times by helping the car rotate on the brakes during corner entry.

And the example with bike brakes I know from my experience - just putting the money into high quality brake pads for rim brakes is way stronger and more responsive than disk brakes.

I just swapped half defective, worn out shock absorbers with a brand new set. Now the new suspension forces the tires to stay more in contact with the terrain instead of leaving it to the springs to uncontrollably bounce around. I definitely think upgraded and if you are serious, adjustable suspension will give you more control for your money both in accelaration, cornering and braking.

The laws of physics are the only ones one cannot break. They say: as long as the braking system is able to stop the wheels from turning, which is the case for all cars out there, “stock” or not, the only limitation to the braking force & hence distance is the tyres’ grip. Sticky, warm, broad tyres are the only ones which’ll do the trick, nothing else. Well done, mate, keep it up! 👍

You are correct. Bigger brakes will not make you stop faster. The limiting factor is the traction your tires give you. It's pretty simple. However, at the track, you only need bigger brakes because small brakes will heat up faster and then become dangerous as they lose their braking power, and other things can happen too, like boiled fuild and such...

They countered by insulting me and stating they could blow through the fancy filter with their mouth more easily so it was impossible not to make more power.

Usually the stock single piston floating calipers on most vehicles are made of cast iron, while the fixed caliper multi-piston setups that most enthusiasts use for brake upgrades are made of aluminum, so usually brake upgrade mods get you unsprung mass weight savings. I have upgraded the brakes on my Mk7 GTI because it's my track car, and the stock floating calipers are perfect for street driving, but would overheat and fade after a couple of laps on a short track where the lack of long straights cannot cool them down between corners, especially when running on sticky track tires. The upgraded calipers (Audi TTS, fixed 4-piston aluminum calipers) even with the larger discs are about 40% lighter than the stock calipers & discs setup, plus the fixed calipers give a much better brake feel than floating calipers ever could, especially at the limit. Again, this is a track car setup, for street driving it would 100% be a waste, just like D4A says.

This.. I'm part of a car club for a specific vehicle model and in the early days of the club (early 00's) everyone was doing the "big brake upgrade" of pulling the bigger rotors and callipers from the sedan model and putting them onto the coupe model, but over the years it's become common knowledge that new oem coupe setups out-brake the sedan setups in every scenario, they were just made well enough that the heat dissipation advantages of the bigger rotors and callipers were completely negligible compared to the disadvantages of the unsprung mass increase even in track situations. So the only way to get better brake performance is to splash out on track specific systems that are lighter, which are few and far between for 25 year old Mitsubishis.. This really clicked for me when I went from 6.5" alloy to 8" steel wheels as a teenager.. I figured wider = wider tyres = more grip = better performance but in reality on a car that weighs less than 900kg (1900ish lbs) the 8" wheels were *that* much heavier that there was basically 0 performance increase. Currently sitting on a much lighter set of 8" alloys and the difference is crazy. Now the limiting factor is that the stock seats dont hold me straight enough to corner any harder lmao

Not only would larger breaks negatively effect the sprung/unsprung ratio, giving worse teaction, & actually negatively effecting breaking distance.. and everything else your suspension does, then there's also the spinning mass consideration. Anything spinning on a car has to be accelerated twice. Once to turn it, & again to move it forward. Twice as much energy is expended in moving a spinning part. Meaning that 1lbs of weight reduction on a spinning part is worth 2 lbs anywhere else on the car. Between that & the unsprung ratio, this is why lighter wheels is such an important modification in sports applications. This is true, of course, not only for accelerating the part, but also for decelerating it. More force is required to stop a spinning part than a fixed one.

Id love a detailed vid on Brake Bias, Master Cylinders etc. Keep on going

Loved the video. What most people probably experience is that their new brakes bite harder after "upgrading", which hopefully feels nice, but does nothing to reduce braking distance at the tire limit. I also wanted to add that even for track day use, all you need is brake pads and fluid designed for track use. Because they work at higher temperatures, and maintain brake force even after repeated stops. Brake caliper and rotor upgrades may look nice, but sometimes actually alter the brake bias front to rear. This may or may not be beneficial depending on what tires you use, and how you prefer to drive into corners. And BTW, upgrading brake calipers and rotors and then still mounting street-type brake pads gets you nowhere for track use. It is really the pads, fluid and cooling that makes a big difference, not calipers and rotors. Unfortunately most brake pads designed for track use do not work well on the street, so you end up having to swap back and forth. Carbon ceramic brakes may be an exception to this.

New breaks decrease braking distance. You start going into nuances which author of the video did not went. He talked about ABS, but omitted to tell you how ABS INCREASE braking distance. That is only natural, because they keep on releasing brakes during braking. And why you are concerned about emergency braking distance? Better brakes will no doubt decrease distance it takes to brake due to tire lockout, but it will come at a severe trade off of braking control. Either way, a skillful driver can replace ABS by just being good by simply disengaging brakes himself when he need to shift directions.

With that, I also kept the stock front brake calipers and rotor diameter, but upgraded to drilled & slotted discs sandwiched between ceramic brake pads. Later I ditched the rear drum brakes (5S-FE 4-cylinder) and installed the rear disc brakes from a V6 Camry of the same model year.

He argues that hydrogen cars are mathematically impossible, and while BEVs are less than hydrogen. What a shill and a clown.

And Unlike EE, this guy doesn't have the voice of Kermit The Frog, which makes his points much easier to follow.

Yes, I want to see a video about master cylinders and piston ratios. Please and thank you. Excellent video. I learned a lot from part 1 and now part 2 of this brake vs tire debate.

You did a great job straightening out your naysayers 👍 Love your videos

Abother brilliant video. Keep 'em comin!

13:50 that point is actually very relatable, I remember playing NFS MW as a kid but never felt the need to upgrade brakes because the stock ones felt very adequate (albeit mostly because I plowed through every corner pressing W like my life depended on it)

In NFS MW it also was the case that all cars had handling good enough so you rarely had to brake, and the speedbreaker made it even better, so brakes were quite unnecessary.

The brakes are just there so you can stop inside the cool down zone after losing the cops or just need to tap the brakes to upset the cars balance for a power slide into corners.
