What I find to be the easiest way to get the dust boot re-installed on the piston is to first seat it in its groove in the caliper, then slid the piston into the boot most of the way. Place a piece of wood in front of the piston so that it can't travel too far out. Apply compressed air from the back of the caliper and the air pressure will push the boot out and into the groove on the piston.
4 yrs later and this video is gold... thanks 👍
💪💪🙏🙏
Well that certainly lowers the fear level of doing this myself.
Best vid on brake caliper rebuild I've seen on UA-cam
* Gold Medal! 👍
nice clear video my Citroen C6 front and rear calipers had UK salt corrosion . the pistons were amazingly rust free but the rubber boots were jammed against the pistons with the swollen rust . the rubber dust boot groove had to be cleaned using a dremel cut off disc .
Superb Gerard you've shown all what i wanted to know, great closeup of what you're doing is well appreciated, thank you .
Thanks Derek, I appreciate the comment 👍
This video is about to save me about 300 bucks. Thank you.
Great tutorial, clear and concise well done
Thanks Frank
Gerard Burke : Excellent video. I was able to rebuild my caliper , 87' Dodge. I could not figure out how to remove piston until your video. Far simpler than rebuilding my destroyed differential assembly. Thank you. USA
Just turn on the vehicle and apply the brake slowly until it pops out. Especially useful if the piston gets stuck when installing it. Also, wear safety glasses. I got brake fluid in both eyes, face and mouth when I was by compressing my piston.
did it many times but its been 2 years from last replacesment so i had to check how to do it correctly. thanks for info.
Great detailed and informative video...Will be doing this soon. Thanks for sharing !!
Thank you
Great video and great work.
Thanks
Ash from Scotland 🏴
Excellent video, Thanks for posting, was very informative and helpful. 👍
Glad you enjoyed it! Thanks for the nice comment.
Thanks on the advice of it not sliding easily. I was getting frustrating it wouldn't go in. Keep the work up.
🙏🙏👌👌
Fantastic video, so glad to see
Thanks very much Wiktor
Really good guide and just what I was looking for. Yeah that piston was mingin.. good job you bought a Big red kit with replacements
Cheers Dan 👍👌🙏
Thanks so much, this helped a lot on my maintenance work!
Word to the wise.... always check your brake clips and Calipers FIRST if you have unusual rotor wear. ;)
No problem. Glad my video helped you out.
My kit came with a wire clip this is for a 2011 lexus is250 front rightside. The video definitely helped
👌
Top video cheers. I'll be doing this imminently on mine. 👍
Good video. However, I would've liked to see more details on how to insert the seal into the grove and the cylinder. I was really hopping for that. The outside of the caliper could've used more cleaning and some paint to keep the rust away.
This vid is getting a bit old but still relevant for many cars. My Nissan Note had a stuck calliper so I took it off but could not remove the piston. I reconnected the hose and tried to pump it out but it did not come out completely before jamming. At around 7.30 you used a flat drift/chisel to unjam yours so I tried that and IT WORKED! Thanks for the tip. I've now got to put the seals and rubber cover back in (pity that bit was missing) and after seeing your vid, I'm confident that it'll be ok. Thanks, Gerald, for the vid.
Thanks Colin, I appreciate the comment ❤️🙏
I wrap half of a plastic bag around the air compressor blower end tightly like plumbers tape to act as a seal and then jam it in as above. May need to adjust the seal diameter with more or less wraps of plastic to get it :) Will get the most stubborn of stuck pistons out this way but beware the piston can pop out the other side with a lot of force so keep your fingers away from piston face and inside of caliper. I stuff the inside of the caliper with a few rags so the piston gets caught when popped out so it doesn't get nicked/damaged. That way I can reuse it if in good condition plus it helps slow down the piston on exit making it slightly safer.
Great tutorial bro
Great video, very helpful!
Thanks Joe
Just bought 4 kits for all my calipers as I wanted to restore them. Mine is a Honda Accord but more or less similar callipers. Glad I searched for this video as the parts are on the way now and I feel a lot more prepared to start on it now. The only thing that I will do different is that I will let the all the fluid go out as it is at least older than 3 years and needs new one. Thank you very much sir :)
In addition to the excellent description of the actual process of rebuilding the caliper, I really appreciated the steady camera work and clear direct narration without rambling.
Too many instructional videos are painful to watch because the camera is handheld (not on tripod) and bouncing all over the place. Don't this people watch their results and realize how bad their video is? Combine that wobbly camera with "instructions" which are delivered with no preparation so the narration is just a jumble.
Gerald's video was lightyears better on both counts, well explained, and expertly filmed. Thank you!
or worse...mind numbing music
Great video
Thanks
good video I would just say the copper crush washers for the banjo union always put new ones in everytime you take it off, to ensure a good seal, for the price of the copper washers i feel it always worth doing for peace of mind & for a complete job, cheers
I agree Brian if you have new washers certainly use them.
If you don't you can test after reuse and confirm they have successfully sealed under pressure etc.
Thanks for watching and commenting 🙏🙏
Very useful information bro plz make video on double piston caliper repair i ll try it on mahindra scorpio of my customer
Love from india 😀😀😀
Fantastic video, so glad to see the EP3 videos back! I'm having the same issue so will be giving this ago. Is the process the same for the rear caliper aswell?
Probably a bit late to respond to your message but no, it's not quite the sane process... Rear calipers are generally trickier - mainly due to fact that there's usually a handbrake mechanism to also contend with... And rear caliper pistons wind in, which can be done with long nose pliers if you're stuck but generally, rear caliper tools are required... Not expensive but can be fiddly to use if you're not used to them 👍🏼
If the bleed screws are stuck it can be a hell of a job doing anything with the caliper. I ended up buying refurbished and trading in the old ones. You get a caliper that is like new effectively.
After that, I intend to keep up with my maintenance more and take the bleed screws out every year or so, apply anti-sieze on them and also push out the pistons and grease.
Many cars simply do not get the attention they need, such as this, and garages will replace pads and discs without giving attention to anything else it seems.
A really lovely video well done sir.
Thank you
Great video many thanks 👍
Thanks Nigel
Top video very informative
Definitely worth the effort (save the cost of a caliper) when you have the time.
i came up with this when i had a garage years ago. if u cant get the ring on the boot to pop into the groove inside the cylinder [and be very careful with a screwdriver, better to cut a blunter piece of wood] pull boot to end of piston so the ring on the boot is over the edge, then using insulating tape tape the boot to the [clean] piston to hold it in position and u can then push ring on the boot into the groove without having to insert the piston.
works really well, as much as i liked the excellent vid i tried for ages to do it his way...impossible
Anyway that works best for you is the correct way. I find in many jobs when I work beside other mechanics I do not agree with their install or removal method, recently watched a mechanic stripdown an in tank fuel filter, I thought he would struggle in many of the ways he approached the clips and seals but did it perfectly in his own way. If it works and the job is correct that is all that matters.
I am glad you enjoyed the video and thanks for the comment Keith
Keith, I am intrigued by your technique for installing the boot but I am struggling to fully visualize your method. How can I get more information on exactly what you are doing to get this item boot installed?
You should show us the most important step of how to put the seal back with the piston
I don't have a compressor so used a grease gun to push the pistons out. It's messy but it does work.
The easiest way is to unbolt the calliper but keep the brake line connected and pump the brake pedal to push them out 👍
Nice in depth video but I think If I was going to go that far i would have kept going and sand blasted and resprayed the exterior of the caliper. A fresh red Caliper on a car like that always looks great.
Thanks Peter
Great video that was one manky looking caliper
Thanks Robert
Very good.
great job
Thank you Patrick
Great video! I was just wondering how you find out what dimensions of the repair kits are compatible with your calipers? When I check suppliers with my car's number plate, there are several alternatives that come up.. (I have a Volvo V40 2013 D2 114hp with ATE calipers).
I like the idea of using the car to push the piston out.
It must just be me but when I rebuild anything I never put new parts onto dirty parts. I always give the whole area a thorough clean.....but it irks me when no one else does. Good info and tips though.
Great vid. Just wondering did you just bleed that caliper that you fixed ? or did you bleed all four as well ?
well done, nice work, but i believe it will be better if you totally rebuild the caliper body before installing the rebuild kit, meanning that a total grinding for the caliper body inside and outside and polishing then painting finally to remove the rust and band it from coming again. this will be much better and will guarantee 100% successfull job. well done again for you efforts 👍🏻
👌👍
Have you ever tried a car value I have used on before you just have to cut the bottom end of the value a bit
Exellent good job
Thank you Marko.
Awesome vid. I can’t find pistons for my Toyota 4Runner 2008 😩🙁
So the dustproof seal is the same on both sides, if turned it doesn't really matter right?
Is it possible to replace the dust boot without removing the whole piston? My brakes work great but the heat from the track has deteriorated the dust boot
You going to be making anymore type r videos? ive just watched all yours lol
Its always best to rebuild caliper, its like a few dollars for the seal and boot, it makes no sense to me to give your original caliper up for an unknown rebuild. Just make sure to use assembly fluid/grease and NOT brake fluid and torque all bolts to OEM specs, any library has Automotive Databases.
Its all about time, if you don't have a lift, then kneeling or sitting on the ground rebuilding a caliper on the car, or taking it off, clamping the hose then going inside to start cleaning and rebuilding it takes alot longer. Especially if you have more than 1 caliper to do, and its on your daily driver.
Excellent video. Is it ok to use a wire brush on a drill to clean the inside of the chamber ?
The less abrasive the better but it depends on the levels or cleaning needed. if it is your only option then go for it, if you can do it another way I personally would.
Thanks for the kind words Wayne
How much roughly would you expect to pay to have the fronts refurbed on a type r (Fn2) on average? Think your garage is too far from me as I'm in Dublin but wanted to get an idea before I decide whether to try myself or not
That's a neat work shirt you're wearing. Where can I get one?
Good video (9/10). If you want full Mark's you need to add a pinch more enthusiasm. But quality content and you dont ramble.
Cheers Mikey, depends on the day mate, I don't tend to fake it on any of my videos. This was mostly an after hours job when the doors were closed. It was all I had left buddy 😆😆😂
@Harold Finch 😂😂
Do you need to bleed every caliper or just the one that you have worked on? Great tutorial
I always bleed all four calipers whenever I have taken a caliper off.
Are the 1993 and 1992 caliper assembly the same for honda accord
Do you ever plan on a headgasket video?
Great video. Very concise.
Can you use silicon grease to grease the seals and piston?
That's what I want to know as well. Isn't silicone and DOT3/4 a non compatible mix?
@@SuperLoffe For lubing inner square seals and piston/cylinder surfaces, it's red rubber grease you're supposed to use in small amounts (it is compatible with DOT3/4 brake fluid). For example on my 08 subaru impreza, the service manual calls for using Fusch Renolit Rubber Grease JP (and when you buy OEM Subaru rebuild psiton seal kits, they come with a small pouch of that pink/redish RRG and also a small pouch of orange silicon grease called Niglube RX-2). The silicon grease is reserved for cylinder outer dust boots for the cylinder and for caliper slider pins and slider pin dust boots. Silicon grease is not compatible with DOT3/4 hydrolic brake fluid. Only the red rubber grease is compatible with DOT3/4 hydrolic brake fluid. If you can't find RRG, you can use brake fluid to lube the inner square seals but the RRG ensure longer life as it's not hygroscopic therefore protects against rust and pitting on the piston much more.
@@JonathanVaucher thank you 👍
@@JonathanVaucher Thanks for this info , nice to know exactly whats correct and whats not, cheers.
However :
you must mention ,,,
those who is doing it
must keep brake fluid
level above minimum line ( Min )
while pumping the brake pedal to
prevent air entering the brake fluid
which will make cavitation and
spongy brakes after brake job .
When you feel spongy brake
that means air in brake fluid
which require more bleeding
while adding brake fluid to master
cylinder and brake fluid reservoir .
👍👍👍
Thanks again .
All good Info.
What kind of grease do you use in the slide pin?
Ooouuufff, that's one stinking brake calliper...good indication of a lack of brake fluid changes...once the piston gets to that degree of damage best to replace as even cleaning the corrosion off the pitting will damage the 'wiper seal/inner seal' in most cases..good to see someone going through the process as you did Ger......
he did replace the piston with a brand new one, it's shown in the video, you missed it completely
That brake fluid was definetly not changed at 24 month .. I usually disasemble it first then deside rebuild or replace whole caliper.
Is all audi calipers like this .that you can hot it from the back ?
I would be concerned using grease on the piston and internal seal. I have looked at several brake manufacturer sites (Raybestos, etc.) and have yet to find one that shows using grease on any parts that will contact brake fluid. They show using brake fluid during assembly of the square seal and piston and the grease is used on the external sliding parts and under the dust seal to help prevent corrosion of the piston that is external to the square seal.
Can't see a problem t.b.h. I must delve deeper though!
Ok, but which way do you put the rubber piece on?
is it ok to pinch off your brake line like that? im scared to try that because im afraid i will damage the brake line.
The flexible brake line can definitely be pinched off. They make a specific set of pliers for the job. They also make small clamps for the same purpose.
If damage occurs, it's because the brake line has degraded and is not safe anyway.
I have the pliers and have used them on multiple brake jobs. It doesn't take much pressure to clamp off the line.
Could a bad caliper cause new discs and pads to shudder after a few months. I have an 03 wrx . Thanks
Yes. It happened to me on an 08 impreza. Caliper piston on the front driver size was stuck/siezed.
very easy way to get caliper out air compressor in the hole work every time.
is there no wire clip to hold in seal
I can not emphasize enough the importance of pumping the piston out of the caliper with the brake pedal with your foot. Air pressure often fails to push a stuck piston out as shown in the video. Hydraulics never fails.
Is that caliper set just for demo? Looks scrapped.
When you take the caliper off, does the brake line leak?
Yes it will, make sure to have a bottle standing to catch it or block it with putting on a blocked brake hose or something like that on it.
Did you replace the copper washers on the brake banjo pipe
No Michael I reused the old ones. No issues after install and driving etc..
A visual inspection of the washers will give you a good idea, if they were over tightened previously you would see heavy markings on them (out of shape)
Iv got new callipers coming so iv ordered new copper washers but if your using the same callipers As you say there should be no issue. Great video btw. Thanks for the reply :)
What kind of grease you put on caliper piston?
Red Rubber grease is what's used on the caliper piston by manufacturers that do not want to put hygroscopic brake fluid in calipers that will be sitting on a shelf and absorbing moisture (aka rusting).
not sure clamping rubber brake hoses are a good idea.... i would just replace them to be safe. and i think its recommended to replace those washers too
Damn that is rusted bad. Could that be the reason my car jitters when braking?
have the entire caliper sand blasted after removing pistons& seals...it looks ancient. Too much road salt
Agree, it's filthy.
It’s not a show car. Does the job. Don’t need to be pretty
Good On You - for wearing gloves! Last video I watched (half watched) the guy was working on a caliper in bare hands and 'twas not a good sight watching him getting brake fluid all over them.
But not good watching all the new stuff going in to a clean insides but leaving the outer body so filthy! That desperately needs sandblasting or soaking in something to at least make it look like it has been rebuilt. Yuk, I would never do that. Do the full job. I also would have put on fresh clean gloves before installing the new seal and piston. Those first pair had lots of dirt on them.
I cant believe you didn't take the pads out and clean the hardware whilst you were doing such a complete rebuild
Hello Stuart,
That was all done previously at another service interval before condemning the caliper failure.
The pads moved freely and there was no issue there, realistically at that time I had planned to upgrade front brake discs and pads but that all changed and have since moved to Oz and sold the type r to another enthusiast, a very bitter sweet moment 😢
Thanks for watching 🙏
Pls put on some saftey eye wear
Would have helped if you actually showed us putting in the piston and rubber
Best way I found is 1) install lubed-up inner square seal in it's lubed-up groove (the inner groove). 2) Install lubed-up cylinder outer dust boot in it's groove (the outer groove). 3) Lube cylinder walls 4) Lube piston's surface 5) Gape the already installed/seated outer dust boot with your 2 finger and insert the lubed-up piston in the cylinder through the dust boot. The outer dust boot is much easier to seat in it's groove before you even insert the piston, and the dust boot is easy to gape and insert the piston through once the rubber is properly lubed-up and seated anyways.
That rotor is destroyed you need a new one also new brake pads and new metal clips to hold the pads
Why didn’t you replace the badly worn brake disc ?
New caliper is like $80. Unless its a project car most dont have time to rebuild
Your not looking at that price for a high end car they. 200 pound somethings if not more
I have 3 vehicles. If I had to do something that took time for one vehicle, I'd just drive the 3rd vehicle until I was able to get it done.
New "refurbished/rebuilt" caliper is that 80$ price, not brand new OEM ones. Who knows if it's rebuilt as well as you would rebuild them yourself. Some factories sell you rebuilt calipers that still have the pitted piston inside of them (they just buff out the rust but pitted spots are still there). Other companies do make things right and install new pistons if required. I'd rather check myself if I need new pistons and do the job right than to rely on someone else who might cut corners round. The worst are those calipers they want to sell when doing brake pads/disk at those 20$ oil change places... cheaply rebuilt ones and you're lucky is the last 2 years before they seize up.
Only half/50% job was done . ....... Why the corrosion expands around the piston area and compresses the boot onto the piston causing drag . The caliper needs bead blasting and painting .
13:18
I like how he didnt actually show installing the dust boot lmao. Cause its a fucking pain in the ass
It is absolutely a tricky job, did not show it because of my hand position blocking and blurred the focus when recording, it was basically unrecognisable what I was doing when I reviewed it, so I re shot the clip after install and talked about the process.
The air compressed didn't work properly because you took the bleeder off. Simple!
I think I'll just grab some rebuilt ones. That brake fluid really dries my hands out.
Gloves help with that. Black nitrile gloves are fairly cheap.

A tip to avoid clamping the brake hose is to buy earplugs, and put one in the hose
Works like a charm, and no risk of destroying the hose by clamping (which means a lot of work)
Thanks for the most useful tip. I was just thinking about what to use for this plugging purpose. Never thought of earplugs, but the kind that mush down easily in the fingers could be fitted inside the line easily enough. Seems the brake fluid doesn't eat up the earplug material, which would be one concern, but allowing the brake fluid to flow out a bit after removal of the plug should solve any residue issues. I already have earplugs around as they are used often where I work.
@@gedgetips I guess if you are worried about a reaction you could just cut of a finger to a new disposable glove and place the earplug in that, and then push it in.
But I haven't had problems the few hours I've had them in though
It's possible that keeping them there for days, weeks or months could be different. But I have no clue actually.
If I remember next time I open a brake fluid bottle, I will leave an earplug in some fluid, just to see what happens overtime.
