I'm an ex-mechanic and found this a fantastically simple to understand, and yet properly detailed overview of braking systems. Well done!

My 2.0 litre hybrid Toyota Corolla estate returns 50 mpg on a run & even higher in nose to tail, stop/ start traffic. The worse the traffic, the better the fuel economy. Plus, if you stick it into sport mode it takes off like a scolded cat with a turbine like howl from the CVT box & electric motor. But it's the regenerative braking that is totally new to me & I love feeling the energy flow around the car. The continuous dance between the ICE, the electric generator/motor and the battery is fascinating! When I first got it I was driving like a bog standard ICE vehicle but after a while you get the hang of speed just being a temporary store of kinetic energy ready to be shoved back into the battery via the regenerative braking. Ready for immediate re-use if I floor it and the motor slurps it back out of the battery to aid the ICE. Losses come from drag, friction, air-con and ancillaries. It's an amazing system. I absolutely love it to bits & it's made driving interesting again after 42 years. I couldn't go back to a plain, non-hybrid. Nor could I go full EV yet as the infrastructure just isn't up to the job yet. Thanks for a fascinating video. Yours is an excellent channel.

Very innovative - but prone to warping because the drum portion was stamped steel if I recall.

I invented a "Y" disc brake many years ago. A normal ventilated rotor that flared to a 120 degree "V". So the caliper was mounted as now except the acted radially. So, you had one external pad in the "V" & TWO pads one each side on the outside of the "Y". So the pistons are radial acting against the curved pad in the "V" float would pull the floating caliper engaging the "outside the "Y" pads. Advantages you ca hope air channels from the front of the car through the body onto the flared Rotors & the back of the pistons to cool the fluid. The rotor is 3x wider on it's braking surface which is at it's largest diameter. The rotor can be half it's current thickness & 2/3 it's weight. Very quick & easy to change a pad set. Disadvantages. Smaller rotor for same size wheel. The same or greater braking pad area. Similar but more effective percentage of rotor cover by pads.

I've been a mechanic for 60 years and have repaired many brakes and still learned something from this video.

Found my new favorite channel! I'm not the most knowledgeable person ever but I've definitely spent some time in, around and on car's trucks and heavy equipment. And within 2 minutes of watching this video I've learned more about the physics of braking energy than my 30+ years of driving experience taught me. I'm super looking forward to binge watching your videos.

During the 1980’s, the transition from asbestos composite brake pad formulas to a less carcinogenic brake pad formulation using Kevlar was developed and patented by a man named Phillip Dougherty. This was the first effective attempt to get away from asbestos based brake pads. Ford motor company was the first to adopt this new technology and was quickly followed by other car manufacturers both in the US and Europe. Great video on a much overlooked topic!

Excellent overview of the history of brakes. Single channel rear only ABS was common on pickup trucks for a while.

I love how we took so many steps in braking-components to now be at a place, where we can even harvest that energy. I am excited for what that whole electric-motor trend will bring to this century-old problem. Also, i really like these deep-dives. Is there anything regarding clutches in the pipeline? For some reason they still feel like magic to me in how they operate.

Braking please. Thank you.

There was also a pneumatic regenerative braking system wich worked by converting the kinectic energy into presure energy with a compressor and an air tank. It was developped in the 70’s

You failed to explain how air brakes work on larger commercial vehicles. They are not simply "pneumatically actuated". The brakes of a CDL level vehicle such as a Semi Tractor Trailer or large dump truck, etc: will have a very large and robust spring that is always applying the brakes and locking them and in order for you to be able to drive away from a parked position, you will have to build enough pressure (typically well over 100 psi), to overcome this large spring that is holding the brakes at each wheel. So the pneumatic system is actually RELEASING the brakes, which will then allow you to drive away. This is why you hear that large burst/ discharge of air when a semi driver applies the brakes-- because they are actually releasing air from the system, which drops the pressure and allows those springs to apply pressure to the brakes; again, the default state of commercial brakes while at rest is to be fully LOCKED. In this way, if there is every any issues with the brakes system failing or your compressor not working or you simply lose pressure through a leak, etc. - it will cause your brakes to lock by default, rather than having a run-away vehicle. You could probably talk about the history and design of commercial brakes as a standalone video.

Excellent job covering the history of braking technology development and the science behind each step of development. Can't wait to watch more of your videos. One early (sub) chapter of the story that I learned of recently... When the metal band around a drum was the default choice, Henry Ford chose to package that feature inside the transmission operating in an oil bath, and acting on the output shaft and thus stopping the driveshaft. It wasn't common on a car brand basis, but when Model Ts were half of the cars on the road in the 1920s, It sure was the brake system for a lot of cars! It did not have a lot of stopping power. Model Ts also had a lever and cable drum e--brake on each rear wheel. In 1928 Model As adopted four wheel drum brakes.

I absolutely lobe these videos about automotive systems and where they came from.

Very awesome video! And it was great to see someone mention the difference between race carbon brakes, and road carbon brakes. A lot of people tend to miss that bit of information.

A positive effect brake technology regulations have had… The iron composition of the rotors makes it easy to source proper and consistent alloy when doing a bit of mold making and casting. It’s not too uncommon and there are a lot of folks out there who have been doing it for years in their backyard. Obviously takes a bit more complicated setup than a simple DIY garage set up to melt copper scrap or aluminum or what not… But it’s fairly easy to get going and not nearly as complex or expensive as an industrial professional setups. A lot of it can be had on the secondhand market because of all the foundries shutting down or it can be cobble together from parts for almost nothing. Then a few times a year when the buddies need things cast for antique restoration or whatever reason… Throw a hella party for an afternoon everybody brings over beer and sweats their ass off helping. Quite a bit of prep work involved but it’s still a blast. There’s just some things that can be done easier and cheaper with a 3-D printer and simple moldmaking techniques instead of designing a cad model for CNC and trying to source proper materials. It has its niche but it’s also A lot of fun and sometimes you just need to part in cast-iron. A lot of at home casters have always appreciated the consistency in the alloys of rotors. Able to be sourced at most scrap yards for less than $0.10 per pound. And gives you the benefit of picking matching sets from the same lot to be sure the alloys are the same.

Top quality video, much appreciated. And as I changed the brake pads on my just the other day and spent a few minutes admiring the design of the sliding pin design - this video really hit the jackpot for me!

In the 1980's Ford widely used a mechanical ABS system on the European Escort. In some countries only on the XR3 models but in others also on normal versions. It consists of two belts (one on each driveshaft) which were connected to a flywheel type device which uses centrifugal force to detect rapid deceleration of the wheels and completely mechanically reduce brake pressure. It was not a very effective system but it was a cheap solution for that time.

You make an excellent point. One feature that prolonged the use of drum brakes was their self-energizing effect. Many car buyers disliked the over-assisted touchy response of power assisted drum brakes, and were content to stay with un-assisted drums long after they had accepted automatic transmissions and power steering. The linear response of disc brakes made power assist more necessary, but power assisted discs feel more progressive and controllable. Front disc / rear drum brakes were an imperfect compromise solution, but still an improvement in the evolution to power assisted, anti-lock four-wheel disc brakes that we are all accustomed to for decades now.

Really very well explained and brilliant graphics. What a great informative video. Clear and concise speech, excellent job.

I'm not sure if it's actually improving brake power. As discussed in the video, virtually every brake system exceeds the acceleration force of a car/vehicle. ABS is there to prevent wheel slip, which occurs when you apply too much braking force. In other words, if you can lock up your wheels, which you can, you cannot brake any 'faster', the limiting factor being what's actually touching the ground - tyres.

Cool video, as a car mechanic myself for 27yrs I found the history particularly interesting. One correction though, you say the automatic adjusters eliminate the need for adjustment on drum brakes at 09:58 , this isn't quite the case. Whilst it certainly reduces the need, the drums still need to be removed periodically to remove the dust and manually adjust the adjusters up (typically 2-3 yrs, about 20-40k miles), if this isn't done the pedal travel will gradually get longer and longer, as well as handbrake travel. Also the shoes will wear abnormally with greater wear occurring nearer to the wheel cylinders pistons.

Great explanation 👌

That is an excellent video and should be used in training new automotive engineers (if it is not already being used that is) If used in the UK a very minor observation to the otherwise excellent commentary is that some terms need to be put across in a dual way such as 'Rotor' in the UK would be 'Disc' and both terms should be learnt as it gives a wider learning scope (understanding other versions of component names is important I feel) Really enjoyed it, great work!

Small thing, I know, but brake drums and rotors are typically cast iron. Unrelated, but to help understand hydraulic systems, I find it helpful to think of brake hydraulic cylinder size ratios (such as described at 7:00) as similar to either a lever with one end longer than the other - like you mentioned - or like the easily-seen gears and ratios on a bicycle. Longer, easier distance traveled by the force of my leg on the bike or brake pedal, put into a smaller gear or piston, converted by the diameter difference into a shorter distance of movement, with a much stronger push than I put in on the other end - and of course the inverse is true too. Hope this helps someone wrap their mind around hydraulics.

No mention of the Ford Model T brakes. Brakes are a single band, originally with wood lining, that squeeze a single drum within the transmission which is bathed in motor oil. Later years used woven cotton material for lining. This system put braking pressure on the driveline. No brakes on the front wheels.
