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

excellent installation of new front break piston & inner & outer rubber seals #

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.

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

You said little grease on the slider pins after you dunked them in the bucket of red grease lol thank you that was funny great video good job

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

[lefterisstasi]

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.

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

[dogbite]

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.

[MrVARhythm]

My gf and I love watching you lubricate pistons.

[starsaan]

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 😂

[jonsutyautomotiverepair]

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 YouTube venture

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

[Dnasty]

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?

[DameAndThatGame]

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
