How to Align a Hydraulic Disc Brake on a Bike

[@DJDeviANT]

The production value on these videos is bloody stellar

[@bandguy360]

when you sell a headset press tool for $85, you can make high quality videos lol

[@emanthegman9511]

@@bandguy360 😂...you could literally get a whole bike for that price....its a kinda ridiculous

I came to this video to pass it on to a friend. Ended up watching the whole thing myself as I was so impressed with the quality and content.

bloody hell mate

[@MA-dg1qr]

One of the best teaching videos I have ever seen; concise, to the point, perfect camera work and expert knowledge. Thank you Truman!

[@Cesar-cm4if]

Agreed! Btw, not sure if you heard about it but you should consider getting an nta helmet like xnito or bern hudson if you have a cpsc helmet. Cpsc is not that safe

[@garretts91]

You can easily get rid of a hard to adjust rub by sliding a business card between the smallest pad gap and the rotor. Lightly pull the brake lever while tightening the bolts.

[@billybass4189]

garretts91 superb tip!

[@nickpickles5327]

Is this good for mechanical as well?

[@blake_rockwell]

Wow, that worked perfectly! Front and back rims are straight as new, 4 years later on my Giant Trace. Thanks!

[@simborandy]

Amazing! Thank you!!

[@davidkopman5710]

I am possibly the least mechanically inclined person in the Western Hemisphere and yet this video helped me fix my annoying disc rub problem in under 3 minutes. Thanks so much!

[@pjclinch00]

Before watching, disc rub, shortly after watching and doing as it said, no disc rub. Job done, thank you!

[@johndelvacchio5590]

I work part time at a bike shop due to my passion for all things bike. I work mainly in sales, I own 2 bikes and a 3rd on order. These videos help me to maintain my own bikes and speak more intelligently to customers who are thinking about buying a bike. The production quality is fantastic, the graphics sometimes used is super helpful. Thank you Park Tools.

[@mlee6050]

How often to do this? I got SRAM red but tempted to swap to a caliper I know that seems to stay centered as piston each side move in

[@foggzie3502]

Had some rubbing on a brand new bike and this saved me a trip to the shop! Thank you so much :D

[@pizzaking7878]

Loosening the bolt, holding the brake, and then tightening the bolt worked for me. Thank you Park Tool!

[@groovy_bear]

Honestly guys, keep doing this invaluable videos and keep manufacturing in the US and not overseas, and I'll keep spending quite a few bucks on your tools ! These are so crystal clear and well produced, it's almost as if we should pay for watching this (not giving you any bad idea...)

[@Slazmoservicing4209]

I've found on so many occasions that having the rider sit on the bike and pull the brake lever while the calliper mount bolts are slacked off really helps fitting. The frame seems to distort and that moves when there isn't any weight on it, alignment that's achieved is thrown out when the rider gets back on. Hard to achieve yourself but when you do it a couple times you manage sitting on the seat to give weight and weight align the calliper.

[@Adventurous_noob]

The best video guide I've seen so far. Thanks!

[@smokeycanuck8058]

As usual, Park Tool is my go-to resource on KZbin for bike service. Just picked up a bike with hydraulic brakes which I’ve never owned in the past, right from the shop I heard a little rub on the rear brake. This alignment of loosening, holding the brake and then tightening is quite possibly the easiest thing I’ve ever done to fix my bike. Thank you.

[@swd542ski9]

Thank you. Less than five minutes and the rub was gone. My first disc brake adjustment and I was nervous; this video is great.

[@DimaGerasimov]

Thanks, this is the only video that helped to get rid of residual rubbing noise. A few other tutorials also suggest similar thing with holding the break and then tightening, but the tip about fine tuning and screwing slower was the one that only this video has.

[@Frank-mn4hx]

It helps me to align the hydraulic disk bakes on my E-bike. The calipers did rub. After adjusting it with help of this video it's fixed. Thank you Park Tool

[@wutzzz138]

Park Tool furthering the progress of amateur/hobbyist mechanics.👏👏👏👏

[@sunray7629]

Thanks for the simple to follow fix - loosen the Calibur, squeeze the brake, tighten.

[@Soandsoguy]

Thank you for being appropriately thorough and authoritative!

[@charvinn]

fixed the grinding sound thanks to this.

[@1590powerhouse]

Thank you so much! you got me back on the road!

[@aymene1995]

I spent hours trying to get rid of the rub, then watched your video, solved in 5 minutes. Thank you

[@erwinagodilla9468]

Thank you so much! I bought a bronco and I only used it 3 times and already hearing a sound in the rotor. Im so happy!

[@elkohr5314]

Perfect 😃 Literally took 1 min to adjust Thank you so much

[@b.l.t.8521]

Have had this problem since last year and I really thought it would be a hard fix but thanks to you it was fixed in ten minutes

[@vigomate6212]

Bought a new bike but had this problem, thanks to the video i was able to fix it even tho i dont know nothing about bikes

[@dalegreenaway]

These videos and all of them are just the best! Thanks guys.

[@deanh7190]

TY! @3:52 I used the folded over business card trick to space out the pads. After adjusting just with the 'brake on' method here, I still had slight rubbing. Now they are perfect.

[@averyhagen5870]

This is the first bike repair video of park I’ve watched, and also coincidentally the first one that’s worked immediately

[@akken2112]

Thanks for the invaluable information in this video. It helped me with my ebike.

[@Nogapniba]

Yeah thank you so much I just got this bike and I was really annoyed with it and finally fixed it with an easy and fast repair with one tool ! Thank you so much 😊

[@RH-mz3jn]

Another excellent Park Tool video. Thanks for the continuing support for we mere mortals of the cycling maintenance world, the information is invaluable.

[@YasmanyPuga]

Your videos are really helpful. You've saved me time and money, and I fixed my bike's little problem easily 😊 I hope you reach 1 M subscribers!

[@vikasagrawal662]

This is Vikas from India. I adjusted the brake of my new Rockrider ST540 very carefully following ur instructions in a closed silent room. All the brake pad noise is eliminated and they spin butter smooth. Thankyou

[@ambarbs]

Great video. Learnt something new. Though I couldn't fix the squeaky noise by adjusting the bolts.

[@parktool]

Squeaks often come from contamination on the pad and rotors. You can try to clean them with alcohol.

[@cocochanel9291]

worked perfectly.

[@raydonluba4821]

I got a cheapish project bike I thought I would be done after this vid but now i gotta watch the rest of ur vids bc u found more problems I didn’t even know about😂😂

[@danielcastaneda742]

Thanks, worked perfectly on my new scrambler

[@richardfabrizio8998]

Thanks for the diagnostic tips. Very well explained

[@kevinhill.8]

Nice! I was taught to use a bright piece of colored paper behind the rotor to help see things, but I will definitely be trying your “backlight” version as it looks even better.

[@lrebollo]

Super helpful. Just aligned the pads of my new bike and now it's noiseless

[@Bad.Rabbit]

It might be too meticulous, but even after eliminating any rub, I like to slowly engage the brake and see if it pushes the rotor to one side. I then crack the bolts lose enough to slightly move the caliper, adjust, and check again. Less rotor flex, less heat.

[@sp00n]

And this should also give you a better bite point.

[@Terra101]

Exactly as im doing! Im not crazy after all.

[@Digi20]

Most of the time this also gives you a better bite point, so its absolutely sensible to do it this way.

[@sebomel4298]

Thank you! i got a brand new bike and it was rubbing one pad and you helped me to fix it.

[@eugenebashmakov]

Take a paper business card, bend it by half, and put it between braking pads. Loosen the caliper bolts and secure the wheel. The rotor must go between the paper "walls" of your business card. Then press the brakes firmly / ask someone to hold and then tighten the bolts on the brake caliper. Remove the business card. You are done!

[@mengzor]

Thank you, better tutorial on alignment than the brake manufacturer

[@majkl4801]

thx helped a lot

amazing, amazing video. I wish more videos were like this.

[@alharvs]

Thank you muchly. Problem solved!!

[@76galb]

Tnx for this video - I go through what you suggested and no noice from caliper anymore

[@rostam238]

my problem is that the gaps are too slim. it doesn't matter if i adjust it to one side or the other.

[@andreiwasfound]

thank you, saved me an trip to the shop, and it was very simple too!

[@sa5er1234]

The have tried it and it worked perfectly.

[@franck_gui]

Another tip : 1) unscrew the two screw of the brake caliper, 2) action the brake on the lever, 3) while maintaining firmly the lever brake, tighten the screw completely. 4) its now aligned, (if the disc is veiled ofc not work)

[@lagwall]

Such a great video!

[@jackknifer1]

Amazing, worked thank you

[@abhinavsthinking4575]

Nice explanation

[@Indicasativa55]

I find loosening the caliper bolts then pull the brake lever tight then whilst still holding the brake lever retighten the bolts and usually that’s enough

[@XerkoGames]

3:37 solved it for my Radcity 5 Plus. Now it's silent.

[@k-kgeri8085]

Thanks man, you help me a lot :)

[@sasayadbapaps]

Excellent tutorial

[@pnpaubrecht8664]

What a great, helpful video. I love the links to fix other problems. I have the Park torque tool, chain spacer tool (is my chain stretched), chain cleaning tool (love it, because I'm not competent to remove the chain for cleaning), some kind of brush for cleaning the sprockets, and a tool to clean between the cogs. Oh and btw, After the prescribed inspections, I loosened the main nuts, squeezed the brakes and then tightened. Problem solved.

[@winstonwithay1980]

For me, it was the spokes of the wheel rubbing against the brake enclosure, so I just pushed the spokes in question inward a bit with my fingers and no more rubbing. Great video nonetheless

[@parktool]

If the brake body is that close to the spokes, it is likely the dish of the wheel is off. The disc side may need more flattening.

[@nickyb2786]

This was helpful and fixed my brake problem. Thank you!

[@SaratogaNovaScotia]

You are a life saver, thanks!! Just replaced my tires and was struggling with the disc alignment. Your video helped me 100% Thanks again!

[@PepperandCaseysRV]

If you hear a noise on your bike, Stop riding it NOW and fix it. Do not wait “ages” until shit gets ruined.

[@emigrant4life]

adjustment during spinning wheel? nice 😢
