#BMW #E36 M3 #Brakes In this video I am demonstrating the process of rebuilding or re-sealing brake calipers on an E36 M3. Similar process would apply to other cars with disc brakes and a single-piston caliper set up.
have done this job 4 times now on the same caliper, and every time i put a new seal in it it broke while compressing it. So i bought a reman caliper and its leaking from the piston seal as well :')
You were able to seat the boot completely around the piston? how did you do the back side (Close to the top of the caliper). I am worried about damaging the boot if I use a screwdriver or something like that.
You're installing the dust boot incorrectly and you don't lube the boot, you lube the internal seal (with a caliper assembly lube). With the correct installation of the boot, it won't pop out as the pads near end of life and with the correct assembly lube you can push the piston in by hand.
This is incorrect. You're supposed to seat the caliper piston seal on the piston in the proper final position prior to inserting the piston into the caliper. You should also lube the internal seal so the piston slides in effortlessly. And third, you should not lube the outside of the piston seal as all it will do is attract dust and grime which could lead to premature wear and failure of the seal.
