4 Mistakes During Disc Brake Pads Replacement On Your Bike.

[@balazsnagy7170]

Man, you just saved me from ruining my rotors. I already chose (incorrectly) metal pads for my Shimano BR-M6000 calipers. Today, few hours before going to the store I stumbled upon your video. I cleaned my rotors and they say "Resin pads only" but this was completely covered by dust, never even noticed it. My calipers came with Shimano G02S resin pads (I checked and realized this only now, didn't need to touch the brakes for more than a year), now there's an upgraded model G03S, which is also resin but a little more durable. Thank you so much for sharing your knowledge, so I didn't end up buying the metal pads! :-)

[@WildMidwest1]

Three tips: (1] I blow-torch my sintered pads every time they are out. (2) After degreasing the rotors with acetone, I perform a light sanding perpendicular to the rotational axis. Then I wipe the rotors with 91% isopropyl alcohol to remove metal fragments and oils that may have deposited. (3) Season the brakes after each cleaning with 6-10 graded power stops. This method seems to keep my brakes in tip-top form.

[@sergioquinonez5475]

Excellent video ...good camera work , thoroughly explaining step by step ...well done indeedy!

[@999DaveUK]

Great tips. Before pushing the pistons back it's better to clean around their edges or you'll push dirt back in and damage the seals. Also better to ensure both pistons are moving in unison by "exercising" them.

[@buildersedge888]

Very informative video. Thank your for taking the time to put this together. The part about pushing out the rotors before replacing the pads was especially helpful. Now I know why I couldn't get my rotor (and wheel) into the brake. Thanks again.

[@marco4570]

Protip: Use two screwdrivers. One from top, the other from the bottom, touching each other in between the pistons. Push the screwdrivers forward into each other. it allows you to put linear pressure on the pistons.

[@ClaudiuB]

I used one thin Allen key. You can insert it all the way between the pistons, but make sure that everything is symmetrical. And then push with both thumbs on the Allen key so it will push the brake piston back, but again, push and place your fingers symmetrically

[@sivram435]

[@beforedawn]

I know this is old but it's still helpful. If you've used ceramic pads, how do you like them? where do the fit between resin-metal? Pros/cons?

[@alanwilkinson9487]

Just stumbled upon this, excellent tutorial, I'm new to this sort of stuff. our local bike shop has closed down recently, so it's a case of, if it needs doing DIY, or go to a shop like halfords and pay the earth for jobs like this. I've just changed my brakes, next job pads... Many thanks..

[@giuze-explore]

Nice tips but one other mistake I learned from another video is to clean around the pistons before to push them inside. So if you have any mud or dirt around the piston, you won't put dust on the ring.

[@Frank-mn4hx]

That's very clear. I have to admit that I almost waited to long before replacing the pads. The pads were worn so far that it was almost metal on metal. In that case I would have damaged the rotor. When I started replacing the pads I found out that the screw holding the pads was stripped. I had help from my colleagues and we decided to replace the caliper on the back. The new caliper had new pads installed. Now we had 2 problems fixed. The squeeking noise is was making and it prevented damaging the rotor. Now it works as new and I can stop saflely. Although I must be carefull not blocking the wheel. It will make the rear wheel slip, wearing the tyre down.

[@knut8154]

Thanks for a couple really good tips! One tip I have is if after finishing you now have rub on the pads, before adjusting the caliper mount, do the pad bedding process as this might fix the rub without moving the caliper.

[@andrewkb5211]

Thank you for such an informative video. I feel much more confident changing my pads now. 🙏👍

[@andrewcosmatos339]

Isn't it good practice to push out the pistons slightly and clean them before pushing them in else you could contaminate the seals which could cause leaks?

[@herculesmclovin]

Great tips thank you. I would mention... Clean pistons *before* resetting/pushing back in. Otherwise you are pushing dirt into the seals of the pistons 👍

[@alfrecletero]

How about resetting the pads before changing them? That way you'll scratch the old pads with the screwdriver and not the new ones.

[@usaisamess8880]

He did that

Glad to see my country Malaysia on the disc.. factory is in my home country, but its super hard to find a original pads for bicycle.. i wonder why.

[@norwegiantroll2480]

Because none cares about Malaysia. Especially Shimano. They use your country only as cheap work force.

[@LetRippr]

Great tips, learnt some great points, even though been doing it for years!

[@MasterFeiti]

Most useful brake pad video I have seen so far. Thank you

[@bazahaza]

Watch the ones by park tools much better.

[@moe9142]

I got some additional Tipps and Information here: If you only touched the brakepads with your fingers, you should be ok by going on a flat, straight street and accelerating to a moderate speed. Then braking hard should be hot enough to heat up and burn the oil. You should have "normal working brakes" after 15-20 times repeating this. To clean the rotors you can put them in a bucket with a mixture of hot water and normal "dish cleaning soap", afterwards spray the rotors with something like "brake cleaner" and some minutes later use a paper towel to wipe if off again. From the moment on, when you move the rotor out of the complete brake, DON'T EVER PULL ON THE BRAKE LEVER, otherwise the pistons will come out and the "brake-system" will leak mineral oil. New brakepads always need some time until they have their maximum braking-power, so wait for them to reveal their normal power before hitting steeper descends!

[@vik6885]

This mistake happened to me while testing the other wheel wher I put the rotor back in and I accidently pulled on the lever of the wheel without the rotor. The pad and some oil came out. I managed to push the pad back in nicely however there is no pressure on the lever now. I hope replacing the oil will fix the issue.

[@moe9142]

@@vik6885 Actually just bleeding your brake should be enough to fix it, I think GMBN also have Videos about doing that!👍

[@flyingscot3666]

thx for your video - learned how to spread the pistons using the old pads - v successful result - much appreciated

[@wilcurran3377]

Excellent video. Clear and concise. Thanks very much!!!

[@wanderer2246]

You said that brakes can be damaged when brake liquid is pushed out of the system, but I had an incident with my Deore XT brakes when brakes lever was pushed super hard (by an obsticle) and I after examination of the bike saw that the liquid was pushed out of the system at the lever side as well as somewhere on the caliper side with splashes left on fork. Though, brakes still works, I didn't bleed them after that yet, the only thing is they feel a bit more stronger with a closer stroke point. Actually don't understand how too high pressure in the system can break them, as then in some critical situations this means you can be left without brakes if you apply too much pressure?

[@denisosipov840]

If you degrease your pistons in caliper, they will be oxidized in feature. You should use some silicon lube on pistons.

[@ethanmoore7648]

So could you use muc-off silicone shine?

[@olliebodman9771]

Changed mine today, but my front brake lever is solid when braking but my back brake lever is spongy but works 🤷‍♂️🤷‍♂️ what do you think

[@jorgeh.gonzalez3929]

Amazing video . Very professional and well details about possible mistakes . Thank you 🙏😜👍

[@johndef5075]

Use plastic tire levers instead of screwdrivers.

[@dominicbritt]

Doesn’t matter if you’re pushing back pads that are due for replacement …

[@fenderstratguy]

Excellent and highly knowledgeable presentation.

[@stoianRT]

Something to add: i also use some sand paper to remove a small layer from the disc pads. the results are really good. So you can clean your caliper and disc but the pads also retain some gunk. This is maybe why you recomend changing the pads before they run out? Try this methode maybe it will work and save you some money

[@M-DIY]

Radu Teodor Stoian use 400 grit only!!!

[@martinparker6536]

also you can heat them with a blow torch to 'sweat' the crap/oils out of the material.

[@joeMopar412]

If you have a minimum 180mm rotor mount, could you use a (160 to 180mm) adapter to install a 203mm rotor?

[@someformofhuman]

Are those Acera components? If so, I have a Tern Joe P27 (A 650B touring foldie) with the exact setup and moreover a coincidence that I need to replace my rear brake pads today. They're so worn down until I hear a metal-on-metal rubbing noise recently. I took out the pads and yikes!! Less than 0.2mm of pads left, it's almost stripped bare nearly touching the metal plates. Oddly the front pads are completely fine. Thanks for the video. I do not mind doing a mini-review of my bike someday for your Channel. :)

[@jordsfjords885]

finally some very good video with great explanation!

[@DuncanStewart-xd1jw]

Might be easier opening the bleed screw at the caliper end when pushing the pistons in, rather than messing about at the reservoir. Works for car brakes.

[@BushmanCanuck]

Safer too...especially sram.

[@No_justice_no_peace]

You'll get fluid leaking out if you do it at caliper end because that's where pressure will be released. High risk of contaminating rotors and pads . If you do it on reservoir side it pushes the air out and the fluid gets pushed into the reservoir instead.

[@DuncanStewart-xd1jw]

@@No_justice_no_peace when you open a bleed screw at the caliper, the only pressure is the head of fluid in the system, which is small. If you have concerns over contamination, attach a tube to the nipple, as is the practice with cars, or just wrap a rag round the caliper.

[@matthewotremba9230]

I keep a bag of tongue depressors around , good for pressing pistons , an cleaning , getting into tight spaces . They are soft , yet rigid

[@johndef5075]

Plastic tire levers work well too.

[@vintagerider4301]

Thanks - removing the screw from the lever assembly is a confirmation I was looking for everywhere.

[@PrzemyslawSliwinski]

From hindsight it appears obvious, doesn't it?

[@Tubecraft1]

Very good video thank you. I might add that if too much force were used with the screw driver a person could bend the calliper mounts on the frame so just a note to only use a twisting action on the screw driver 😊just like you did good job

[@snaky1337]

after putting the new pads , do I need to do something more special to do on the first ride

[@calvintanner7897]

What if you experience burning in the brake pads ? Can that mess up the calipers for both front and rear rotors ?

[@Musicalbluewolf666]

thankyou , i have been looking for this video. my disc brakes also have a pin rather than a screw.

[@rothschildkilledjfk6237]

You should of cleaned the Pistons before forcing them in like that, You just forced dirt back in which will led to a lazy piston just sayin, Ohhh and you should of lubed the piston with the brake fluid ur manufacture use.

[@Tubecraft1]

How would you recommend cleaning the pistons ? Depending on how I do it could I end up pushing more dirt into the seals than if I just push the pistons back ?

Do i have to remove the wheel or can i just remove the calipers instead??

[@cha-ronfaheemtaylor4556]

thank you so much for sharing this information. i am new to the concept of disk brakes. i was assuming the brake pad material was a choice of quality, so i was going to buy any type this time, but steel pads the next time.

[@makantahi3731]

it same as on car : usuall organic pads for easy braking, semimetalic for higher temperature and ceramic pads for race but it does not work good when are coold

Had a issue with my shimano xt brakes. Couldn't get the pistons back far enough. Wound back all the level adjustment and the free play screw at the top. Got everything back together but when I applied the brakes oil came out from the lever. Luckily it was the pressure relief valve. Readjusted the the components and system operating correctly.

[@supersai4198]

I didn't degrease the disc at all, works perfectly with my new brake pads. My bike is 2 years old and first time changing front pads only. Feels brand new!

hi, my friend is using shimano altus br-m365 brake setup and he is wondering are G01A pads compatible with his brake set?

[@popitn2nd]

New bike, new brake pads, new rotors. Does it need more fluid if the throw is too low when braking?

[@macro182]

what if i'm not able to push back pistons even if i've opened the bleeding screw? do you have other suggestion more than open the entire caliper? for example using heat to let the housing of the pistons dilate?

[@EV-js8ku]

Thanks for the #3. Helps me a lot

[@kongyb5452]

Hi, i would like to know is it normal that rear brake pad is closer to the rotor compared to the front? I am using ultegra hydraulic disc brake.

[@callumw9067]

do you not add some copper grease to the back of the pad?

[@makantahi3731]

why, to reduce drag of braking?, joke, it is used on cars, not need on bikes

[@nicolasbrisebois-tetreault8050]

My pistons are not resetting completely. I tried to do the trick with the bleeding port open. As I unscrew it that spill. Is it normal? I guess there is to much oil in it.

[@catkoala]

How about to clean the pistons? Doesn't matter that you reset the pistons if the pistons doesn't move evenly because of dirt n stuff.

[@mattl1762]

I remember when i used my pads so much that the braking surface seperated from the backplate, it flew straight out. Hope mini's, still on my bike today, never been re-blead and still works perfect!

[@jimmihenry]

Yea, was good idea ti take a look at your vid, ife already overseen the print "RESIN ONLY"! On my motorbike i was able to chose organic, or metalic brake pads. This a comlete different story... Tank you! ;)

[@showze21]

excellent how to do disc brakes video

[@Pillokun]

Dont do like I have done, ie keep the bike near the kitchen and the fat from the frying has contaminated the pads... new shimano xt pads in the gutter.... But the thing is, i have new pads(cheap ones) and have cleaned the disc but yet it does not brake as it should although the pressure is there so it does not feel like it needs a bleedeing.

[@lazurm]

If the pads became contaminated from, say, lubricant picked up from the road, wouldn't working the pads with a #220 sand paper and alcohol deal with this issue effectively?

[@mtbboy1993]

It took 4 weeks to wear resin pads out on resin only rotor, So I had to switch to metallic. This was on 160 rear 180 front, and non finned pads. I knew my rotors would wear out, but as I only use metallic pads, I just installed metallic pads and tested it out, it took about 4 months to wear out the rotors.

[@843thebear]

Useful video , thank you.

[@Qnexus7]

9:30 yep exactly what happened to my front brake: pushed a lot the pistons, lost like 60% of the oil from the reservoir. but the question is: why you saying that the whole system is broken in that case?? isn't it enough to re-bleed it?

[@Qnexus7]

ok got it, thanks

[@JM.TheComposer]

How about the mistake of not checking the piston movement? I replaced my hydraulic disc brake pads due to poor braking power. I eventually figured out the real reason was one of the 2 pistons was seized and not pushing on the pads!

Also, Shimano says to only use alcohol or soapy water, to avoid damaging seals

[@smallhatshatethetruth7933]

@@educationalvideos4151 I push out the pistons then use a pipe cleaner soaked in mineral oil to get the dirt off of the pistons

[@andrelloyd4010]

A fifth mistake is to assume NEW pad faces don't need degreasing prior to fitting. Part of your pad fitting regime should be to degrease new pad faces which takes only seconds with an atomising degreaser. Removing a few thousands of an inch off the new faces using a fine grit paper is further reassurance that possible contaminants in production - packaging - storage or shipping are removed prior to fitting. Best wishes and happy pedalling !
