Audi 100 C4 brake bleeding, brake pad replacement, caliper replacement, stuck caliper piston
It's time to replace my leaking and seized caliper with a new one (I got a used one on the cheap)! I replaced the brake line that was leaking fluid when I started bleeding the brakes. The left rear caliper was also seized. I loosened and lubricated everything, which was a bit of a hassle! I replaced the brake pads on all wheels! I didn't change the rotors because they were 13 mm thick and slightly worn. I pressed the piston on the rear caliper with a grinder wrench and pressed the front one in by hand. All problems were successfully resolved.
