I put new rotors and pads on the wife's '85 300D today. Everything was going well, then I noticed I couldn't compress the outboard piston on the passenger side. So the pad wouldn't go in.
Upon further inspection, the outer seal came off in my hand. The piston seems frozen, I can't force it back into the bore.
My question is, oh wise readers, can this Bendix caliper be rebuilt? Or is it time to replace? I sprayed some WD40 on it and will see if it's freed up tomorrow.
Thanks to the things I've learned and the confidence I've gained from this forum, I was able to tackle this task and save several hundred dollars.
