Great video George! When I watch British car repair vids I’m amazed by the rust, but then I remember you’re an island nation surrounded by salt water.

Your videos are the best for guys like me (amateurs), every details well explained. Thank you Bro!

Nice video George. Just a little tip.. when installing outer dust boot it is easier to put boot on lip when the piston is out of calliper. Slide boot to the lower edge of piston and then slide the piston trough boot.

you can also pump the brakes to pop it out that's what I did. great video

I have been waiting for this video for a while. Again, very detailed video. I love it! Thank you!

Great video, very clear on the procedure. I resealed all of my callipers last year and this year I am starting on the fronts with new callipers, painted and new discs and pads so will be watching out for your video on the discs and pads changes to get some more great tips. Keep up the great work George.

Great video George! Love the step by step process

it is VERY easy to tear or puncture the seal. once you get piston in with seal, use an airline to pressurise the boot. This will make it expand enough to seat itself on the caliper. This is the only way which worked for me. Also remember to make good the points where the pad edges contact the caliper. Rust stops the pads moving in when they wear which side-loads the piston to the point where it seizes.

Great to see someone repairing. Any Muppet can bolt a new part on. I prefer to repair not replace.

Brakes 😬. You have done great job mate! Keep it going 👍

Literally saved my life thank you!

Another fantastic video - great, clear explanation of work needed and work carried out. I use silicon grease on the slider pins of my brake calipers. I would be confident to strip down the calipers on my brakes after watching your video. Thank you.

Hey, nice video thank you for helping me and my e87 250.000km ! I’m from Belgium but nobody does that as well as you in French 😂

Good job George! I have Discovered you bevause of timming chain for my n47. You have no ideea how much it helped me that series. Greetings from Sweden.

Great detailed video as always. Cheers 👍👍

Cool video George man

Best to put boot on inner end of the piston and seat seal while it's on the piston before pushing it in .then push piston trew New boot only takes seconds and no screwdriver stuffin needed

Great job!👊👍

Great job

Great vid George

Maybe a small tip out of 100s 😂, maybe a skinny screwdriver pushed down the bleeder screw hole to push the piston. Also cheers. Looks really easy, gonna do mine soon now, cheers

Good video mate, i don’t do value or rebuilds due to the extra time needed, but if they’re cheap enough you’ve given me something else to think of!. Good luck In your KZfaq venture

Thanks for sharing George, they get in bad nick at times eh

Very nice video, Thanks!

Vídeo muito bem explicado parabéns 👏

great video mate

Really great video you make it look so easy 10out10 nice one George peace

great job

My gf and I love watching you lubricate pistons.

... and this is the trickiest bit... ...so here's one I did earlier... Me: Dammit!

Great video. I dunno how you got that last lip in that’s currently where I am stuck. However I didn’t use any grease and I think the kit is not an exact fit. Getting the caliper cylinder in was a bit difficult also but getting it out was a breeze. I sprayed compressed air in the brake line hole and it popped right out 😂 used wood blocks to catch it of course. I was also wondering if I soak this in degreaser can it damage any of the internal components?

next time try to blow some air with compressor. It will push piston out of calliper in seconds. Just be careful with your fingers cuz it pops out quickly and piston bumps into calliper wall. Ask me how I know

It's very important to point out that you should NEVER use any type of grease on rubber seals except for silicone based grease.any Petroleum based grease WILL cause the rubber seals to swell and cause the caliper to stick/seize.

I'm doing mine now on the front, can't get the outer boot on caliper it seems real tight

George, another excellent and very informative video, Are you a mechanic by trade? Just found your channel recently and I’m well impressed with your knowledge and tips.

I use an airline to pop the piston out

I had to do the same in my 120d.

I have same issue new to doing me mechanicals on my car?

Where do you find the rebuild kits? Ebay best bet?

Hi George, Where did you find the rubber plug you have on the end of the brake hose? I have been looking for something like that a while. This will remove the need to have something clamping down on the hose.

Hi George. Great video, just curious where you got the parts from? Ie the piston itself, did it come as a complete kit. The biggish places I've tried don't sell them and BMW only sell the piston as part of the main caliper so it becomes really expensive!

I have the same caliber and the same metal ring came off when I took away the old piston boot. I just can't understand how to pop the new boot in, because there's no groove where to pop it in 🤔. It just comes right off if push it all the way in, because there's nothing retaining it.

Great vid as always 👌🏻 Did u have to bleed the brakes when you re installed the calipers?

Nice video. Do the rear rotors need doing ?

Great video, just one question, how do you get the trapped air out from the callipers?

Compressed air will pop a stuck piston out.

Hi george thanks for your video, I am trying to fit out piston boot and it will not fit no matter how hard I try, what else could I try?

🙌🏼

Great Job 👏🏼 - I would have greased the inside of the piston housing too. To get a bit more grease in. Keep up the cool vids ✊🏼

Bmw want them dry to extend the life of the caliper...🤣🤣🤣

Thanks, that was very helpful. Do u have to bleed the brakes after reinstalling the caliper?

Nice video George, Where did you get the brake line caps from?

Oh for crying out loud, you're a life-saver (if I haven't botched up the job too much already). I was under the impression that no grease was compatible with brake fluid so I only used brake fluid to lubricate the O-ring and piston surface. Now the piston is in crooked. I'll bet if I used some of that red rubber grease, I wouldn't have had such a problem sliding the piston past the O-ring. Be careful when you Google "red rubber grease" because a lot of the results will be that Lucas Red "N Tacky grease which is something different. I see off to the side that Castrol sells a "Red Rubber Grease". I've seen it in a Castrol container and in a white container on Amazon. Now I've got to get me some and hope I can remove the jammed piston from the caliper without destroying the new rubber dust cover. Actually, why not destroy it. They're cheap. Thanks for posting your video otherwise I would never have known about that red rubber grease.

Hey. Where I can get this cap for dripping brake fluid? Super video

for some reason i cannot even get that inner seal back in it just wants to keep popping out on the opposite side i have in. IDK What to do??

Do bmw sell those pistons oem? Or you buy them aftermarket? Cheers

Nice video yet again George. Where do you get the orange gloves from? Are they expensive for a box of 100

Why didn't you blow the piston out with compressed air? Out of curiosity... That's how I always do it

good job, my rear pad is grinding metal on metal because it wont retract

does it drive a lot better?

How many miles?

Did u have to bleed the brakes after installation.?

Why the hell didn't you use air on the bleeder hole and blow out the Piston 😢

No bleed process?

Good but cant believe you didnt clean the calipers up more and paint them ??

instructions unclear: i popped the caps but got arrested....

The intent was fine, the advice is bad. Don't grease the pistons or piston bores. You will contaminate the brake system and fluid by doing so. If lubrication is needed, use the correct brake fluid for your car, fresh of course. And do not use grease on slide pins or anything rubber. Silicone paste should be the only lubricant that touches rubber, and same with slide pins. Silicone or ceramic only. I've seen this mistake made too many times. You will be buying new calipers and brackets if you do the same.

stick a shim and pump the brake next time works like a charm

My car has not even got over 3k miles & i have alredy changed brake disck brake pads & both front caliper & handbrake wires 🤨 & o it is not a bmw...

Only use brake fluid when you rebuilt the caliper, nothing else, you have already contaminated your oil with grease.

You didn't bleed the refurbed calipers before declaring the job was done. I can just see an inexperienced DIYer following your video and then taking the car for a spin with no brakes.

the pads and rotors were done on that car, putting them back on was retarded, also outer seal should be set in then piston placed through it, this video shows what not to do

What a waste of life , waiting for the ads to finish

Where can i get these caps that stop brake fluid from leaking?
