Tip for a fast, accurate and fine tune when centering the caliper: as on disc brakes, release the center bolt, so the caliper is loose. pull hard the brake lever, then tighten the center bolt progressively so it will not affect the correct alignment.

Mechanical disk brakes next?

@parajuanjo

Michael, to tune mechanical disc brakes, here is a fast and "quite accurate" way: as you may know, the way to adjust the reach of the pads, is generally with an allen key, on the inner face (like if it would be the inner piston) across the spokes. so, first you find the proper reach as you like. then you release the two adjusting bolts at the fork, so the caliper comes loose. then, you add 2-3 points to the bolt (it will close the gap). then you press hard the brake lever. then adjust both bolts. then undo the 2-3 points to the reach adjust bolt. so it will sepparate the inner pad, and it should not have any rubbing.

Frank, I am actually rather familiar with adjusting the disk brakes on my Synapse, and I appreciate your input. I have TRP duel caliper brakes and have some clearance issues and more importantly, I am hoping Jon can explain it in a way that friends of mine can understand. What I tell them goes in one ear and out the other. It would be nice to send them to a video rather than re-explain it on a weekly basis.

Or even brakes.

TKs, best 5 minutes I have spent on my brakes. Toe in was brilliantly easy.

When the brake pads are glossy but with some life left I usually use some fine sandpaper and they're back to life, thanks for the video!

This is great. Thank you so much. Most other videos make brakes look so complicated, this made it much easier to understand.

Man really really thanks for the video, I personally know all the parts except for the last one when you show how to correctly toeing in brake pads, that's exactly what I was looking for! MANY MANY MANY THANKS, SUPER USEFUL!

I have a bike with disc brakes and a bike with rim brakes. Gotta say, rim brakes are much easier to maintain.

I thought so too, but eventually decided I needed gain proficiency in maintaining the disc brakes. Lots of information on GCN and the latest edition of the wonderful Lennard Zinn book. I still find rim brakes easier to work on, but discs generally need a bit less frequent attention, and are much better stoppers on the steep wet roads where I live. A different fettling skill, but well worth the effort to acquire and practice the new skills. 👍

How often do you need to do anything with the disc brakes though?

@stevecarpenter7462

6 жыл бұрын

Ian Loughead 😀. Not very often, thank goodness! Mine started to rasp slightly on the front. I had a slight warp on the front rotor that I solved using the rotor truing attachment on my wheel stand, which helped but didn’t cure the annoying problem. Cleaning the pistons solved the problem completely. So discs are great, but not maintenance free!! (Bless Shimano for using mineral oil!)

I have a quick release frame, so nearly every time I remove a wheel and replace it, I need to reset the calipers. The rotors are easily bent - I need to re-true them every couple of weeks in my experience. Just little things that become almost daily maintenance tasks that I wouldn't have to worry about with rim brakes. It's a serious PITA, but the better performance of the disc brakes are worth it in the end.

ZDW95 I agree. I have QRs with my disc bike and whilst I don’t need to reset the Calipers that often, it is a skill well worth learning! I’m lucky to travel a lot with a bike (Cape Town tonight!) 😀and don’t take the Di2/disc brake bike. Lithium batteries in the hold isn’t great, and whilst my velovault is a great bikebox, I don’t want to risk those rotors. Easier to fettle old tech in a hotel room!

That’s right, I AM worth it! Thanks Jon.

Thanks for this then! I got both brakes a little bit tighter than they were before, based on inadvertently pinching the rear wire at the tube router by mistake and then making some unsuccessful adjustments after that. The fact is I have only recently had old style caliper brakes and at times they've been like a Chinese finger puzzle at times. But today was better!

This helped me sooo much when i had side pull brakes. Not so applicable now that i have linear pulls but still a great vid. Keep it up GCN

I was having problems with my rear brake calipers not giving me any strength for some unknown reason. I did my first half century and the rear brakes simply stopped solidly clinching until the point that I could put my bike up on a stand and press the rear lever and I could move the rear tire with my hand. It was tight but moveable and when I was riding it was practically useless. I was going to take it to the shop but using the steps that I just saw in this video it worked just fine. I mean I feel like a champion. THANKS!!!

Thanks for the video, very helpful! I couldn't see any adjustment screws on my caliper brakes, turns out it was the big boy in the back. I can finally stop losing my mind at the sound of pads grinding off wheels.

In addition to wiping away the brake dust/road detritus, I add a dash of chain lube to the pivot points of the calipers each time I need to do a bike/chain cleaning. (remove any excess oil)

Is chain lube special or just an oil? What about WD40?

@georgehugh3455

4 жыл бұрын

@@Icewing10 Chain lube is not especially special, although there are GBs of space dedicated to the topic. Any lightweight (runny) oil will do; the other camp uses forms of wax. Oils are better if you get rained on / go on wet roads. WD-40 could be used if applied *_very regularly (almost each ride),_* but it has elements of mineral spirit qualities that make it good for cleaning and removing greases/dirt, but also means it evaporates away.

Thanks , solve my brake problem !

#gcntech: When cutting the outer casings for shifting cables, be sure to file the endings flat, otherwise each of the wires that form the outer casing is formed like a screw driver, and is able to cut through these plastic ending caps. And if you don't file the cutted endings of outer casings for brake wires, it may happen that a piece of the cutted wire of the outer casing is preventing an easy gliding of the braking wire. Especially when the outer casing is needed to cover the full distance between shifters and brake levers, it saves quite an amount of weight, when you use fasi outer casings, they weight only about 20 grams/meter, instead of 40 grams/meter like conventional casings, as fasi uses alloy instead of steel.

Good video

Using old school mtb with V-brakes: Attach the pads roughly on place, don't tighten much yet. Use a rubber band (from old inner tube) to bind the lever near the grip. Loosen pads and align them, tighten up properly. Long pads (70 mm) don't need toe-in, shorter ones possibly need some. Remove the rubber band, make sure both pads come off the rim evenly. Because the tire is far wider than the rim, make sure nothing rubs when the pads travel away the rim. Sometimes you have to repeat the process a few times to get everything right.

You're welcome!

After running over rough road, always check your caliper centering. Quite often wheels will flex and the rim surface will actually whack into one of the pads causing the caliper to misalign, leaving you with a rubbing brake pad. A good reason to not keep your pads adjusted so close to the rim when not applied.

@ryanotte6737

5 жыл бұрын

I second this. I also think those that are setting their brake pads very close risk locking up too easily during a hard/emergency brake. There is always that tendency to grip even harder as we brace ourselves against the forces under braking. I don't agree with the almost touching the handlebar mentality for brake adjustment either... don't want to risk bottoming out with the handles. I compare a 2mm hex key/wrench against the rim-pad distance and that is about right to give some good responsive pull with a bit of play room on a lot of road bike brakes. 2mm is about right as an initial guide.

Thanks sir.

GOD BLESS YOU !!! 31 dislike probably they have disk brake 😅thanks for help like always !!!😜

#askgcntech When can we expect GCN Tech to make some videos on cable-operated disc brakes? You always seem to assume that disc = hydraulic, but it ain't necessarily so.

Need trick j(speedy c.) I wonder what the difference between cables some are smooth and some are not? Pat from Belgium 🚲

Hi GCN, I have one of those quick release breaks where you can open the break wide so you can remove your wheels without doing anything else with the breaks. however, I'm running 32mm wide tires and I have to deflate the tires in order for me to remove it. Is there a way where I can set it up so I don't have to keep deflating my tires?

Cheers mi duck

Great concise explanation! Thanks so much! Is this the sequence in which to do these checks? I tried getting my brake pads close as possible but when I tried to center the calipers after, it messed up the distance of the brake pads to the rims :D But I didn't try it while keeping the brakes engaged. What's the reason you do that? Thanks again! Also, is there a playlist for these quick tips videos?

When you tighten it with the barrel adjuster, how do you make it loose again? Do you have to unscrew the bolt where the brake cable passes through or does it just loosen the more you use your brakes?

Again, this video seems much more aimed at those who already have a fairly good understanding of bike maintenance and / or with fairly high end bikes. Can you recommend a really basic / total novice video for those w hybrids?

I have Rim brakes and am considering going to disc, the question I have are there any comparisons between Shimano and SRAM non-cable. I still hear a lot of people having issues with Shimano so I’m curious. Thanks!

I recently bought the wrong brake pads because of a faulty description on the webshop. They're the Shimano R55C for ceramic rims, and I have aluminium rims. Can I still use them? #askgcntech

are metal ferrules better than plastic ones for both brakes and gears

Question: does force required for braking vary between various producers of brake caliper? Example -I have the bTwin ELOPS 500 single speed bike with OEM brakes, that takes strong action on brake lever to stop the bike. I was thinking to change front brake with Shimano 105 calipers. Will the amount of force on brake levers reduce by that? What would?

#askgcntech Hello, I recently bought full carbon clinchers (Fulcrum racing speed 40 2017) How do I maintain, clean the brake pads, knowing that I cleaned my former alu clinchers pads with some dissolvent ? Thanks!

#askgcntech I know this isn't that relevant but what bike were you using in your 5 minute brake tune up video? Also I just watched your video where you had a discussion with Emma about 650c wheels. She said I wouldn't have got those results without them but I was told that with 700c you go 1.5 metres further than 650c. So how come she did so well with 650c?

I just replaced shimano BR-R561 brake calipers with 105 ones on a cube attain gtc sl 2018, the front braking feels good but the rear brake lever feels stiff which is new. The cable housing no longer seems long enough to cover the cable all the way from exiting the frame to sitting inside the brake barrel adjuster. Is there a likely issue? Thanks. #askgcntech

I have a carbon bike, with Carbon wheels which may need new brake pads soon I was wondering what type of carbon pads can you recommend? thanks I love you channel

How do you adjust the brakes on direct mount brakes? One of my front brake caliper is closer to the rim then the other. With direct mount there seems to be no center bolt to get the brakes lined up. #askgcntech

If brake shoe is overhanging the wheel rim, it creates a lip on the shoe grabbing the rim and causes brakes sticking. Check this before cables, levers, and everything else.

Hi there, If i toe in the brakes will that reduce wheel locking up?

what is the size of the centering screw on the caliper? What size of an allen key does it require? thanks

Can you use carbon pads on alloy rims?

Chain can put lube on the braking surface and it is need to clean it with degreaser.

Do you have an equivalent video for disc brakes?

please do this for canti's. 10Min will be acceptable.

This is a weird ass question but I see alot of riders with their caliper adjustment knob/cam lever thingy in the open position with their brake cable tensioned that way. My thinking is that this was always intended to be closed unless you needed extra room to take the wheel out. Correct? Or am I missing something here?

my brake pads are touching my wheels. my calipers are a bit short :( do you have any idea or any diy or should i just replace it?

where should the fine adjustment lever on the front of the caliper be set?
