How to Rebuild a Brake Caliper Fast & Easy

[@jimosullivan1389]

Red Rubber Grease is totally compatible with DOT 4 fluids. It can be used to pack the dust boot to prevent ingress of salt and muck...unlike the Dot 4 fluid.

[@FastFixYouTube]

Hello. That’s good to know. I’ll definitely do that next time. Seems like that step would increase the life of the boot. Thanks!

[@retydown7521]

@@FastFixKZbin There is no need to pack the boot the boot will allow air to pass but not water or dirt. If you pack it it could make the boot pop off under air pressure.

[@kennyh5083]

@@FastFixKZbin You do NOT have to install the dust seal over the large dia. part of the piston first as you did here! Just install it into the indent on the piston where it is supposed to seat, and then push the piston into the bore all the way, and then push the rubber seal in with your fingers into the outer bore indent where it is supposed to seat, it goes in no problem at all! Then install the metal ring, and your done!

Didnt realize till like 6 hours ago calipers can be rebuilt, so im going to jump to it and do the same on my pickup. Beats paying a lot for new calipers, and just as easy to snap in a new piston as it is to replace a whole caliper. Good video!

[@FastFixYouTube]

I hear ya! I didn’t think about rebuilding until I got quoted the price for a new one. It’s definitely easier to buy rebuilt, but if you can rebuild for a fraction of the cost, why not? Just keep in mind it’s a bit tedious and will take some time 👍

[@peterzinia3767]

Yup! But when you try to get a caliper rebuild kit(seal & dust boot) at a parts store they look puzzled & tell you caliper rebuild kits don't return anything on there computer search. They want to hose you by selling an overpriced rebuilt for 60$ or more. The kits are around 10$ & they don't make as much if they sold them.

[@biffybilliamson]

Don't know if it's because I'm female or guys just like to assume I don't know anything. But my Volvo has very expensive parts and usually way too much money. $600 Canadian per caliper. I already replaced the back caliper and started seeing the videos for repairing the calipers. Now I'm hearing "you should never cheap out on parts" "it's incredibly dangerous to repair the calipers, just buy new ones" and garages actually getting angry at me for asking... This seems pretty simple and my calipers were in fine working condition before they were pressed in by the wrong tool, the wrong way.. the repair kits I found are only the gaskets. Should I replace the entire piston?

[@derekmolina9198]

DO NOT crimp the brake hose line this guy did! Unless you want more problems. Here's how to do it: Before you remove the brake line, disconnect the battery. Slightly depress the brake pedal. Slightly less than 1/2 inch after the pedal touches the pushrod and use something like a stick or dowel to hold it there. Now get to work. Doing this moves the piston past the inlet and return ports of the master cylinder so no fluid can leak down from the reservoirs. You'll just get a few drops out. If it's a metal line going in I clean and place the dust cap from the bleeder over the line if it's going to be apart for a while. You disconnect your battery because you probably don't want your brake lights on while you're working. DON'T CRIMP YOUR BRAKE HOSES KIDS!

Thx . I really didn't want to crimp. Tried it your way and it worked

[@bleach_drink_me]

That's not a bad idea, I usually just keep a bolt,nut and 2 copper washers on hand that fit in the brake hose where the banjo bolt goes. Will give your method a go.

[@Pr3lude9]

This did save me. I rebuilt one rear caliper last year. Used a little pick to get the piston seal in. Pushing it with your fingers is much better, and a lot less select words.

[@McRae2730]

PLEASE don't crimp a rubber brake line. You can collapse the inner lining and then when you apply your brakes, the fluid travels down the brake line to the caliper as it should. However when you release the pedal, because the hose is internally collapsed it acts as a 1 way check valve, the fluid cannot return back through the hose, therefore the caliper remains seized. Another method to keep all the fluid from dripping from the brake hose when you remove it, is to press the brake pedal in about 1/2in with an extendable rod, or I've even used a brick. This means the brake lights will stay on, so you may want to disconnect the battery. (Remember your radio code) No more than 1/2in tho, that way the piston inside the master cylinder is moved from its resting state and mostly covers the holes leading down to the brake lines, therefore drastically slowing the drip of the fluid. Great vid, just wanted to pass that info forward.

[@FastFixYouTube]

That is an excellent tip. Hadn’t thought of that one. Figured the crimp method wasn’t ideal, but didn’t know of a work around either. Thanks for this it’s greatly appreciated.

[@JackRR15]

Interesting. I've seen a lot of pro mechanics do it and no warnings like this.

[@seanbarnes9021]

Happend upon this video randomly glad to see people still out here rebuilding brake calipers. It's trial and error with the dust shield but once you have done a couple you can be in and out in like 20 min start to finish. $4.99-$12.99 vs $100-$300 well worth the little bit of effort to fix it. Me I rebuilt the whole thing. Replace the slide pin boots and bleeder valve as well. Literally cost me a total of $10-$20 per caliper and thats all they do in china with your core you give back then ship it back out to be sold as a remanufactured caliper.

[@FastFixYouTube]

Exactly right! So so much cheaper to do it this way and if you’ve got experience, you’re gonna be able to knock this out pretty quickly with little frustration. Most people are doing this for the first time, but hopefully after they completed once they’ll be able to do it again and again in the future and save a good amount of money. Great work and thanks for the comment!

[@blazeaglory]

Im rebuilding a1990 Honda Prelude 4WS and everything under the hood and wheel wells is basically BLACK with thick grime. Good thing about being covered in 30 years of grime is once its cleaned off, you can see all the original metal treatments and coatings. I always thought the calipers were a grey color(online rebuilt calipers for sale are a dull grey due to being soaked in acid bath to remove said black grime but also removes any metal protection treatment) but in reality, they're a golden zinc color. I spent days gently cleaning and soaking in simple green. Lightly scrubbing with a brass wire brush. Lo and behold, the once velvet black calipers are now a greenish gold zinc color! I keep imaging how they looked new, contrasting off the silver rotors. I don't know if i should paint them with a high temp rotor paint tho just for future weather and temp proofing because, even tho the zinc coating looks great, i don't think it will hold up much longer and some areas have been scrubbed off almost completely. But man they look awesome tho! 30yo calipers that most ppl just toss out or replace for the dull grey "rebuilt" calipers(basically same exact calipers just acid bathed and rebuilt). Shoot i might just buy the online ones, paint them and save the zinc ones for posterity lol

[@FastFixYouTube]

Wow, I love this comment! I’m also a fan of the zinc color and if pressed, would keep it zinc for as long as possible. But you said it yourself, already worn off in areas and will soon giveaway to rust. I like the idea of keeping them around for posterity. Nice garage decoration 👍

isnt there a retaining clip for the caliper boot?

Just don't crimp off the hose like this guy did. FAIL!

[@flyboy2610]

An alternative way to get the boot back onto the piston is to seat the boot in its groove in the caliper, then slide the piston into the boot most of the way. Put a piece of 2 x 4 in front of the piston. Apply air from the back of the caliper and it should push the boot forward into its groove on the piston.

Hey there can you please show us how to disassemble rear caliper for Cadillac dts

[@timrussell1559]

Something that gets overlooked quite often when rebuilding a caliper because the vast majority of people don't know about this - is the seal that fits in the bore is tapered and needs to be installed so that it faces the correct direction. The seal is tapered so that the piston will slightly retract when there is no fluid pressure on the caliper. This keeps the pad from pushing into the rotor when the pedal is released and causing premature pad wear. People may not believe this is true but it is indeed a 100 percent verifiable fact

[@FastFixYouTube]

Hello. Great comment! Thank you for sharing 👍👍👍

[@FaszSzopóGoogle]

So does that mean the thicker end goes in first? I haven't noticed any tapering yet but that would also probably ease the installation of the piston when it's first pushed into place. I'm always slightly afraid that I somehow wringle and dislocate the ring upon insertion.

[@MegaMidds]

Is there a mark on the seal to show which way faces out?

[@rolandotillit2867]

If you don't have an air compressor, can you use a slide hammer to pull the piston out?

[@andrewf2630]

Put a small wooden block, about 1.25in in the caliper and depress the brake pedal about 5-10 times til it is pushed out .

[@FastFixYouTube]

Hello. I’m not sure I’m understanding your question completely, but yes the seal should slide down the entire piston. It won’t cover the piston, just fits into the lip of the caliper. Hope that helps.

[@tengzturiagaiii3185]

Where does the metal ring go? On top of the rubber boot?

[@FastFixYouTube]

Hello. The metal ring secures the rubber boot to the caliper. Notice a groove machined into the cylinder near the outside. The boot goes in, then the ring goes in to secure the boot. Hope that helps. Thanks for the question and best of luck to you.

[@morrylauder7534]

But I don't have an air compressor. Am i going to have trouble getting the piston out?

[@FastFixYouTube]

Short answer is yes, you will. The only other way I know of is to remove the caliper and depress the brake which will force out the piston. It’ll be messy… have a bucket on hand to catch the brake fluid. It’s highly corrosive to paint amongst other things. Best of luck!

Hello. I assume you mean ‘piston’ when you say the ‘caliper’ came out. It should go back in. I bet the metal retainer ring is keeping it from seating back in the cylinder. So, remove the rubber boot and inspect the cylinder. If the retainer ring is still installed, remove it. The piston should go back in when you make sure nothing is blocking it. Hope this helps.

[@rednroll1]

I have a small tear on the outside of my outer seal of one of my calipers. I'm not seeing any brake fluid come out of the caliper. Will that be a problem as far as brake caliper function or is it the inner seal which creates the seal, and the outer is just prevents dirt/dust from getting into the piston area?

[@FastFixYouTube]

Hello. Good question. The inner seal does keep the fluid in. The outer seal protects the cylinder from dirt, debris and brake dust. So, the caliper will function normally until too much debris gets in and starts to cause problems. They can last for quite some time with a torn outer seal, so my usual advice is to replace it when it starts to make noise. Hope this helps.

[@kingmonkey88]

Once the outer seal is torn. Dirt and water will get inside and rust up the caliper around the inner seal. This will corrode and pit the piston which will then seize up. You can get seal and piston kits to refurbish calipers.

[@AmarnathJambunathan]

Piston will rust if the outer seal is damaged. Rust will stop the inner seal from working properly and piston wont retract

[@JSB2500]

The replies here are correct: corrosion and seizure WILL happen. I reckon ALL the many calipers I've fixed or replaced, failed because either the piston outer seal was split or because the handbrake shaft was split - both causing corrosion then seizure. The repair kits with the seals are very cheap (~£6) and easy to fit.

Hello. There have been some useful suggestions for people that don’t have air compressors so search the comments a little bit and hopefully you will find something useful.

I think I have a similar sound, on the pedal release tho, if I remember correctly. After discovering both front discs were scorching hot last week, I deattched the calipers from the discs and tested them by pressing and pumping them today. Front left seemed a bit harder to press in. Then, pumping the brakes to push both pistons out simmultaneously, the front left traveled less distance compared to the front right. Also, part of the dust boot on the front left is not stretching out evenly around the piston. So, I'll be doing the seal rebuild this week. Anyone thinking this is the reason for the brake/caliper drag on both discs? OT, I've learned that air in brake lines/master cylinder can cause a sinking pedal, but can it cause brake drags? @Fast Fix, did you replace the piston too? Did the rebuild eliminate the noise? Also, did you have any brake drag?

@@AngryAnR hello. Definitely don’t use a hammer. Something is wrong if you’re reaching for the hammer. I’ve been there, then regretted it. Ha. There must be something binding up the piston. Have you removed it then checked for obstructions? Look at the cylinder walls and make sure they’re smooth. If you see a gouge or something similar that probably means the piston didn’t go in square and roughed up the walls. Also, measure the piston and make sure it’s the right size. Could be that it’s too long and bottoming out. I wish I could see what’s happening and offer an precise solution, but unfortunately we can’t accomplish that through comment threads. If you can’t get it to seat you might have to bite the bullet and get a remanufactured one from the store. I’ve had to do that in the past and assume I’ll need to do it again at some point.

[@Northwesternforcefield28]

Crimping the brake line is like bending a phone cord in one spot over and over and then expecting the inside to be fine and charge your phone. The pressure from clamping even once a brake line that’s starting to deteriorate inside can break the inside of the hose structure enough to cause the pressure to not flow right and your new caliper to cease from a lack of brake line pressure..

[@FastFixYouTube]

Hello. I got these from carparts.com. Sorry, I don’t have any links or part numbers. Thanks for the question.

[@Hempie1000]

Note that it's not the rubber piston sealing ring that causes the problem but of course the damaged dust cover that's responsible for letting water in and causing the piston to become rusty. The rust then causes the friction and may eventually lead tot leakage. So, if you notice a damaged dust cover then you can begin right away with your repair job as this will inevitably lead to the mentioned brake problems.

[@FastFixYouTube]

Correct! 👍👍👍

[@bajaaddict]

How do you put that seal ring back in?

[@bajaaddict]

Not exactly sure where to put that metal ring at.

[@FastFixYouTube]

Hello. The metal ring holds the rubber dust shield in place. It will be the last thing you install. It fits in the groove machined near the lip of the cylinder. I know that didn’t get shown in the video. Sorry about that.

[@kevinmaas3046]

Why didn't you show the metal ring? That is the hardest part that I try to figure out now...

[@FastFixYouTube]

Hello. The metal ring secures the boot to the caliper. Look on the outer edge of the cylinder. There will be a groove. That groove is where the ring goes. The ring is installed last right after you install the boot. In other words, the ring secures the boot to the caliper. Hope this helps.

[@hnng3919]

@@FastFixKZbinyour caption says to install the ring between the piston and the dust shield. Shouldn’t the ring sit on top of the shield (on the grove) so it’s between the shield and the caliper?

[@rbspider]

I would suggest cleaning the caliper housing before rebuilding , chemical and wire wheel. All it would take is some rust to destroy that new assembly

[@FastFixYouTube]

Good tip 👍

[@terrymcneese8474]

Very informative

nice work

[@FastFixYouTube]

Thanks! Appreciate you taking the time to comment 👍👍👍

I use a plastic fork to get the old oring out so it can't scratch the bore.

[@FastFixYouTube]

Wise move!

[@BobBob-pf3bp]

Gonna try to rebuild mine from a 80 lotus esprit, Hope it works.

[@FastFixYouTube]

Best of luck!

You just taught me somethin I will always know how to do now man subscribing hope you do well and thank you

[@FastFixYouTube]

You bet! And you’re welcome. Thanks!

[@reza_dc2]

what size compressor did you use to push the piston out?

[@FastFixYouTube]

Compressor size doesn’t matter. It’s an 8 gallon compression.

[@reza_dc2]

@@FastFixKZbin thanks ~ so I can buy a small 6 psi compressor with a 110 psi , hopefully that works.

[@mitchjenks8636]

No grease go inside that piston how it slides back and forth if there's no grease in it you put it back in dry is that the way it's supposed to be and if it is wouldn't that just cause a lot of wear if it's sliding back and forth and back and forth and it's dry

[@FastFixYouTube]

Hello. I may have not shown in the video, but use DOT 3 fluid to lubricate the piston. Yes, putting it in dry could cause premature wear on the part. However, the piston would get lubricated when the brakes were used, so it'd only by "dry" for a moment.

Thanks for sharing

[@FastFixYouTube]

You bet! Thanks for leaving a comment 👍👍👍

[@andypalmer7903]

Nice vid, good luck

[@FastFixYouTube]

Thanks 👍

[@rocketroy469]

What about the slider pins . As the calipe moves in and out it slides on the retainer bolts. These become just as corroded as the piston.

[@FastFixYouTube]

Yes, good point. Those are worth changing / cleaning if part of the problem.

[@lulubliz6405]

That can make caliper stick too. That's why they call em slides!😉

[@burtreynolds3143]

looks like the same kit and caliper set up from a Cobalt or HHR.

[@FastFixYouTube]

They could be the same.

[@brysonmarlin9756]

Why didn’t you show putting the metal ring back in ?

[@FastFixYouTube]

Hello. It was an oversight on my part.

[@brysonmarlin9756]

@@FastFixKZbin do you just put it back in ?

[@FastFixYouTube]

Yes, pretty much. It’ll go in very last. It just slips into the grove and presses the boot to the caliper. If you’re able to do everything else in the rebuild, this will be no problem 👍

[@Tonythebarberfl]

Mines not going back in still attached to car

[@FastFixYouTube]

Hello. What exactly isn’t going back in?

[@dariuszszewczyk3106]

Brilliant.My mechanic say you can,t remove pistons on modern cars.

[@FastFixYouTube]

I’m unsure if that’s true, but it seems like it’s not true 🤷‍♂️

[@charon9205]

😂

[@bottmar1]

Should have used the brake pedal to push the piston out. Much more controllable and will work every time. Compressed air will fail to get EVERY stuck piston out.

[@FastFixYouTube]

True enough, just messy that way. 👍

[@bottmar1]

No more messy than air blowing brake fluid out. Just have a rag and a pan handy. The fluid drops straight down from the caliper.

[@RaduMichael]

I'm almost convinced you set the dust cover the other way around.

[@FastFixYouTube]

Hmm….well it’s worked ever since the repair, so if I did, ahh well.

Why did you not show installing the metal ring??

[@samuellandis6046]

Sorry, just read on e of the other comments that asked my same question. Sry

[@FastFixYouTube]

You're good. I should have showed that, but I made an error in the video.... Hope the video helped otherwise

[@glenglene8473]

you did not show when and how to put the wire ring back.

[@FastFixYouTube]

Hello. Sorry about that. If I could edit it in, I would. KZbin doesn’t let that happen, however. The metal ring goes in last and holds the rubber dust seal to the housing. Hope this helps.

[@zeketv23]

should have show us how you put back the metal ring the right way

[@FastFixYouTube]

Hello. Yes, that piece of footage was regrettably left out. However, it is the last thing to install simply slip it over the boot into the groove. You can’t miss it. I hope everything works out! Thanks for commenting and have a great day.

[@GoldSK96]

Thank you sir!

[@FastFixYouTube]

You’re welcome!

[@abyssalsoul6216]

My technique when installing the piston and boot is to place a towel on my lap, place the caliper with the opening facing out ,then use both hands to guide the piston in. Your tummy acts like a back brace.

[@FastFixYouTube]

Another great tip! Yes, do what works for you and that sounds like a good idea for all 👍👍👍

[@abyssalsoul6216]

If you are not sure which way the boot should go on look at the old one to see if there are any markings such as manufacturer or even a part number scribed on the boot. With genuine Toyota boots ,the markings face out. I will be doing this job soon using genuine honda and will report back

[@FastFixYouTube]

Excellent advise! A good reason to use Toyota boots! Hope all goes well for ya!

[@efrainsantiago7265]

I saw that he didn’t put a littler bit of grease on the piston in the back it would have gone in more easily

[@FastFixYouTube]

Good tip 👍

[@DosieOne]

you didnt show where the metal ring goes

[@FastFixYouTube]

Yup, forgot that step. It secures the boot to the caliper.
