- Front brake caliper overhaul rebuild Honda civic. I am overhauling a front brake caliper on a Honda civic. I use a foot-pump and modified tyre valve stem to make the job of overhauling the caliper easier. This method allowed me to insert the seal prior to the piston, and therefore be sure it was seated properly in its groove.

There is no shortage of RUclips videos that demonstrate how to rebuild a disk brake caliper. Most of them skip over the part that involves installing the dust boot because that would extend the video by a couple of hours and demonstrate just how little they actually understand about how to do this properly. Most of those videos contain one or more viewer comments that describe the technique of using low pressure shop air to help seat the boot. Rarely are those comments ever detailed enough to help someone visualize exactly how this is accomplished. This video however does an exceptional job of demonstrating this process and thus turning what would otherwise be a very difficult job in to one that just about anyone can do. This is a very well done video. Thank you very much for making and posting it.
Why did you take it off the car? Pump the brakes to pop the piston out. Waaay easier.
you dont need a valve and air pressure to pull out the piston..you have to press the brake pedal first to pressure out the piston before you remove the flexible hose
why not push the piston out by taking pads when caliper is still on car or at least brake line still attached and just let brake pressure push piston out a lot quicker than screwing around with tire vavles, just be careful not to let brake fluid get on any painted surfaces
this is exactly what i was looking for. google is so smart that it reads my mind & put it in front of me. excellent demo.
When you said that you've previously "knocked" the piston out from the back, what did you mean? Now you say you should be able to get it out with "just" the foot pump, as if you got it out some other way initially. Some key details are omitted here.
It’s no wonder back street dealers hate you tube when you’ve got a guy like this showing you how easy it is.great stuff mate.
On my BMW X5, We moved the piston out with the brake pedal before removing caliper, stopped it with a block of wood. THIS IS A GOOD VIDEO.
wow man!!! now i can rebuilt my caliper!! you saved me a LOTS of money thanks so much!!!!
Making that valve stem into a tool to get the piston out is key to the whole procedure. I wish that you would have shown how you made it. It's not clear to me where to cut or how to shape it. Did you use a grinding wheel? I don't understand how it bolts into the hole when it's not threaded.
Excellent video, thank you. I like that you did it with very basic tools. At 67 and a lifetime of DIY on cars, I learned from your lesson.
Just rebuilt an old subaru caliper using this as reference. The valve stem + footpump to get the dust boot over the piston was a particularly good tip!
I´m just a "youtube mechanic" and this repair was super easy following these instructions. Thanks!
First off you shouldn't clamp the brake hose!!!!! The hose can be damaged internally and you won't understand why the caliper is sticking
But how would you prevent all brake fluid from running out without clamping the brake hose?
You can use silicon grease too...lots of bad information here.
Excellent! The two who left a thumbs down must have been a dealer service who didn't make an easy buck!!!
great tutorial but i cant understant your accent
Thank you for putting together and posting this video. It was nicely filmed and, as an engineer, I can say that your method was very well explained and technically sound/logical. I was fairly certain I could sort it out on my own but having your tips and techniques in mind allowed the job go far more quickly and easily (and without some potential pitfalls) that it likely would have otherwise. In short, it allowed me to rebuild the calipers for my wife's car and saved us several hundred dollars in new parts that were really quite unnecessary and I had fun doing it! Thanks again and I'd encourage your to post more videos like this one that so many folks can learn and benefit from.
Thank you! for such a positive and detailed comment.
+backstreetmechanic Copper is the pigmentation in hair.
Excellent demonstration with no distracting music or unnecessary commentary.
Air to extend piston unnecessary.
I like your technique putting the rubber boots first then piston with a pressure. I have a trouble putting it. I use to use other technique by putting the rubber boot to piston then fit in the caliper. Sometimes lucky takes a few minutes.. sometimes takes an hour :)
Thanks for the nice tips and please make a smile to a camera (scaring me Lol)
He IS smiling!!You should see him when he's annoyed!!
uknow an easy tip on refitting the seal is.. where the seal is the most difficult to reach around to seal onto caliper, simply rotate the seal so the unsealed area is visible & then seal it up
ie rotate the seal say 45-90 degrees & the unsealed area will be visible & easy to work with.
dude the trick with the foot pump is genius! I've been screaming at my stupid caliper for an hour now struggling to get the bloody thing back together, thanks :)
Fantastic! Blowing out the seal with compressed air is genius! Not even the Civic repair manual suggested this. All other instructions & videos I saw about getting the seal installed were hit & miss affairs, I will surely do it this way. I am in the process of rebuilding my Civic '95 front brakes & I will do it this way. Thanks for the genius trick.
My Hero!!!!
Thanks a million , You have made my day.
Excellent!!

Man oh Man This is by Far the best Caliper rebuild video i have ever seen, i have just bought new calipers for my ford escape, wish i had seen this video before.
Great technique using the valve stem. I will be using it now. Thanks!!
For those that may question why rebuild? In my case a caliper rebuild kit without piston
(my piston is not pitted ok to use) is $4.99. A Wearever Remanufactured Friction Choice Brake Calipers are between $65.99 --$73.99. And you still have to remove & replace it. Also if you are driving that particular vehicle to parts store you have to lay out an additional ( but refundable ) core charge of $75.00 and go back for the refund.
@JOEZEP54. The greatest technique is using the brake pedal to pump the piston out. Works on every one of them.
Another reason why pistons rust is because people wait too long before changing the brake fluid. This fluid attracts moist over time and needs to be changed every two years.
This is the first video on this I found that shows a great way of getting the seal back right. Just put it in before the piston, then put the piston in and block it, and pump the seal back out with air, genius!
I did this job myself for the first time yesterday and I really struggled with that seal. Now I know what to do next time. Thanks! 🙂👍🏻
I took my caliper apart, clean it, put silicone grease on the seals, put it back together. works fine now. cost me maybe 1 cent worth of grease.
By far the best caliper refurb video on youtube...pure genius
Hello sir...
Can somebody tell how to install a air nozzle in caliper for air pres i dont thnk i could install it if so then which nozzle u recommend to install & how to take it out after duster seal pop out please made a video on it
This is the most imposratnt part i pop out duster seal for your calipers..
Thanx & WAITING FOR U ANSWER
REGARD : HASSAN
The "slightly rougher" - but equally effective - way to get the piston out is to stick a metal rod that fits through the hose-hole loosely, in - caliper in a vise - and give it a whack with a hammer. That works when the piston is genuinely stuck solid & no amount of air will budge it - it will hammer out easily. If you (cough) don't have a new seal to hand, you can let the old seal sit in some atf for a few minutes - ATF contains good stuff for seals, the seal will emerge newly flexible, not swollen & nice & supple. Give it a good clean with tissue & she's good to go.
Usually the groove the seal & dust boot sit into will be mangy, the piston will be mangy but the caliper itself will be pretty mint inside(grooves aside). You can give the piston a good twirl inside some sandpaper & it usually comes up clean as a whistle & clean the grooves as well - they need to be spotless.. You can then re-assemble the lot, it will still be tight as factory, it will function perfectly for years more & you don't have to go shopping.. Also, if you have rust building up in your calipers, your fluids no good - it's absorbed water. Clean fluid does not allow rust to develop, water in the fluid does - so drain ALL the fluid & start again with fresh.
One of them vacuum oil-suckers is the best brake bleeder ever invented - use a bit of rubber hose on the end of the hard sucker hose, pop it over the nipple & let it suck - no dicking about pedaliing pedals, no helper required & it will bleed the hardest to bleed system going in 5 minutes flat. Fellow Paddy btw.. enjoyed the vid.. :-)
Front brake calipers of my Civic started leaking when I was doing brake pads and I was pushing pistons back in. First time ever front calipers have leaked and both on same car! I suppose it's because of rusty piston tearing seals apart and it's not worth it trying to fix it with new seals alone? I ended up ordering new calipers because guy at the parts store told me that new seals+piston would be almost as expensive as complete caliper. Unpleasantly expensive. Now I'm afraid to touch the rear brakes, lol.
BMW E36 owners if you are trying this method, it won't work for you. The ID of the seal is super small so it won't magically pop onto the piston and come out like that. We tried on our drift car. You will need 4 hands and working the seal with J hooks like a tyre bead to pop it onto the piston. Once it's on then you can use the air trick but it's pointless because you will use a G-clamp to push it back in. Still thumbs up because this video is how I did it on my Berlingo.
p.s The only reason it's difficult is because the seal keeps bending out of position awkwardly. It's like trying to build a wall out of cheese.
never mentioned the metal clip that holds the rubber seal (that covers the piston) into the caliper
These are the precious secrets you cannot find in a book...The foot pump,the tyre valve,boot in first..Wonderful wonderful stuff! Dying to try it all out...Anybody with a seized caliper piston ??
ToneDeafecation One of the best maintenance vid's I've ever seen. Hats off to this guy!
Great video, just remember to SMILE, you saved yourself a fortune doing it your self.
Saving money is always worth a smile :). Keep up the good work
You are the Man! Thanks Brother not to many good detail videos out there..
Much thanks . I'm going to do the same. 2011 lexus is 250 front rightside caliper piston pitted
I like the technique, EXCEPT, you did not replace the steel ring which secures the boot seal to the caliper body groove.
Well the concept was right - but I am surprised that you didn't get the caliper scrupulously clean before kitting it out. I would use a spray can product labelled 'Brake Clean' prior to fitting the rubber and rebuilding the caliper.
thanks for taking the time to do this. we are learning from your life experience. thanking jesus as well, for you!
Thank you for very educational video.. Do you think that new parts be worth it, i mean, new caliper cost a few tenner.. At least, always may be could to clean these parts properly, before fit new parts in, what you think..?
That's a crafty approach with the foot pump! Well done video and very helpful on doing the brakes. Considering myself fortunate to have found your guide.Thanks.
If you can push back the cilinder that easy by hand,
you have to much
backlash?
I don't understand why so many mechanics don't use the brake pedal to pump the piston out hydraulically. It will remove the piston no matter how stuck it is. I've done this for many years.
Not fully sure you had the best approach, but the proof as they say is in the pudding, my favourite way is to remove the pads by releasing the bleed nipple, then retighten and press the foot brake firmly to the floor, making sure to place a pan to collect the fluid, out it pops and just clamp the pipe and remove the caliper.
Funny but in the past I have inserted the boot onto the Piston and then inserted them as a pair into the Bore, figuering it was easier than inserting the boot first.
Mr Spence Eng
Wonderful job! Thank you :-) I had no idea how to get the rubber boot back on until I saw this. Much easier just to remove the piston and follow your method.
Great Video! Well done!!
I had answers for all I needed in one video! May God bless you!
Thank you very much!
Very Nice...especially the piston re-install steps..pretty slick. Thanks...
Great Job Mate ,,So now i know the Best way to get it Done,
Cheer's
Valve stem? I got one but it didn't have that connection at all to the brake caliper. Can you give me more info, iten nr dimension etc /Regards
Remove brake pads then press brake pedal a few time until the piston pops out ..You don't need to use a pump this way.
Just tried this and it just blew a hole in the seal which I had waited for weeks to get to me in Bermuda. I guess if you are close to a seal supply you are ok to give it a few goes
Explanation and presentation is so clear well arranged. I as a layman do appreciate your effort.
Thanks for the video, it's nice work, great tips for inserting de seal using the hand pump.
Just wanted to say THANK YOU VERY MUCH. I managed to test my caliper using the technique your shown on the video, Highly appreciate your help on this.... :)
You did a great job. Thank you for making this Video.
top man , great video ! greetings from carrickfergus :)
hi great video. how did you connect the foot pump to the caliper. can you post a link to the connector. thanks
How you used air to put the boot onto the piston was like an epiphany to me. Thanks so much.
Thank you sir!
Don't listen to the no smile comments. It's who you are--and no one will mess with you as it's intimidating.
I pushed the piston out directly with a 10 mm dia. wood dowel thinking I was short-circuiting the need for compressed air and the jerry-rigged valve. Imagine my chagrin when I saw the compressed air used again for advancing the seal/boot! Now I'm thinking of replacing the caliper altogether as I've not yet purchased the rebuild kit.
excellent video ,and great skill in putting the dust boot and piston in to the bore. Thanks!!
R u sure you can't use caliper grease? The ones you use for guide pins....
Like your idea of using a tyre valve. Genius.
You sir are the man :) i was struggling putting the rubber seal on the piston, because on the japanese cars the seal is hold by a metal ring hence you cannot put the seal while moving the piston inside. You should put the seal first and then somehow snug the piston in, however some seals have very small center holes, so its crazy hard to do :) but using air to do this seems to make it an easy job.
I have a Lexus GS300 and rebuilding my brakes now. You are correct in they have a spring clip to hold the boot in place, very fiddly. The method I used is to insert the square shape seal in the cylinder, then push the piston in till the shoulder is level with the groove for the boot then fit the boot. Using the air to push out the piston, slowly, and the boot then fits into the outer groove. I have tried lots of methods and found this works best. Sorry but your method can tear the boot if its a tight fit.
Excellent video.
Top Video. Quality job. Thanks for saving us the research and trouble.
I like this video alot but just a tip for some: I found a $22 used caliper on ebay and that was with free shipping. Some salvage parts people on ebay give such cheap used parts that a rebuild becomes more costly due to labor and the rebuild kits.
wattn` Scheiß.... nix versehen und langathmig.... echt Scheiße
Where did you get the valve stem to pump air in the caliper
Wow, after trying a different method for 3 hours I found your video. I just finished my caliper paint and rebuild on my 06 S2000. Thank you so much!!!
👍👍👍
Top of the morning to ya Shamus!! Potato!!
too late i tear the rubber on mine
You have explained things well, but why go to all the trouble rebuilding the caliper when you can buy the caliper rebuilt ready to go on for only a few bucks more? I just rebuilt a caliper with pistons from both sides for a versatile tractor. Kit was over $200 and took lots of time and frustration. Used calipers for this tractor can be $1000 Rubber grease? where would you buy that? I just used brake fluid to lube piston seal etc. Thanks for posting this video.
Thanks for the video, I'm thinking may be better off getting new brake calipers for both sides and be done with it
Thank U very much I like your creative work especially the hand air pump
اشكرك كثيرا لقد أعجبت بعملك خصوصا استعمالك للنسخة اليدوية ( Arabic )
Good process. Clever use of air pump and valve stem. Good that you used new piston.
Suggestion: To ease removal of rust from seal groves use Naval Jelly. If rust is light and you have time you can use 50/50 water/white vinegar and soak overnight. Naval jelly is faster and better though. It will not harm the critical surfaces.
@x-man5056. It would be more clever to pump the piston out with the brake lever. Works every time.
@@bottmar1 Might work too good. You only need to get the pistons out slightly unless you are doing a dismantle. The brake lever definitely moves the piston well, just don't go too far doing the circus act (lever up here, caliper down there), and pop the piston(s) all the way out. A short piece of strap the same width, maybe just a little thinner than the rotor, would do it. Pull caliper, slip your shim in there, pump them out like no tomorrow. All good.
Excellent Video!! Well my friend now I know how to set up a complete new break system for my 20 Year old Audi, which i really like and want to keep for many more years. Just get some used ones, get the kits and rebuild them and stick them in, test them properly and save much money. Thanks my friend, Roland from good old Germany. Well that's it, look around in RUclips, to learn how to repair your car, made in good old Germany from people from abroad. Hey that's it thanks
Good job MacGyver thanks
IT WORKED. Your method for seating the piston boot(s). Tried 3 other ways that failed. Yours took less than 2 minutes.
Recap. Fit boot onto base of piston. With cylinder end of boot extending past piston. Leaves room to squeeze the boot. Grease the cylinder to accept the boot. ANGLE the Boot and piston in so most of the boot is in the cylinder grove. GENTLY work the rest of the boot into the grove with screwdriver. Went easy with all that grease and no piston to block the boot. THEN seat the piston into the cylinder. Press piston all the way in. Listen for the boot to drop into the piston grove. AWESOME. Thank you, Mitch
Much appreciated from The Florida Panhandle, Wiregrass area! Workin on my Nissan Titan. Question: why not put brake fluid on piston b4 installing it into new seal? I didn’t read all the comments to see if this was addressed already, my apologies if it was. Thx again!
Fantastic video. The H*ynes Manual for the Jazz describes calipers that are completely different to what's fitted and hence no good for working out what to do. (Your Civic is the same as the Jazz)
I wasn't sure how much to push the new piston in before doing the foot pump trick, over did it and split the seal so beware! Luckily the old seal was OK and I held the piston in place using one hand against the seal whilst pumping with the other and the technique worked like a dream.
Thanks for saving me a lot of time and effort!
You do it badly
Bruh disnt even explain one thing
Great video. Did you just clamp the tube so it wouldn't spill? Is there a way to plug the tube. I want to paint the calipers. Wondering how to stop the liquid from pouring.
Great video, thank you. Do you know possible causes of a seizing calliper?
why you just cant use car break pedal to push piston out? :)
i did with break pedal, no external tools was needed.
you can just you lose more fluid
good idea to to replace fluid any way unless you know it's new
That is what I did too … but … I started with the right front and want to do all of them and changing my brake fluid. But now the front right is out I have no "pressure and fluid left to push the other ones out. So this video solved that problem :-)
👏👏👏
If you have a sand blasting booth you can add to this job a rust removal and a paint job on the callipers, then you get virtually NEW callipers, did this on my land cruiser and they work great!
managed to do this today, trick is to put new dust boot over piston first and then seat in calliper, I had to start engine to get brake assist to force the old piston out !
Is there not a thin metal ring inside too?
What the fuck is tumb 😂😂😂
Super cette technique avec le gonfleur . Merci
very good video clear concise
👍
Hello! If i grease the rubber seals from the inside of the calliper cylinder, is it ok? I mean, the silicone based grease wouldn't mix with the brake fluid?
I have been struggling with similar brake seal. This tyre pump trick is brilliant .. I’ll try this tomorrow ... thanks for a great And helpful vid.
This was helpful
Not gonna lie though I only understood about 25% of the dialogue 😂
you guys wanna know some acid trippy shit. i have this issue and im watching this video as i replace mine and as im watching this video there are garden people from the complex trmmig hedges and stuff in the background
just like in this video... trippy
Hi, I'm doing caliper rebuild, ant search your video. Finally I successfully did it your style inserting caliper rubber boot by pumping it..much easier and safe time :) Thanks again for sharing
