95 R100RT Brake Problem

It looks as though my left caliper is leaking between the two halves. So I was thinking about getting a couple rebuild kits and going to work. But...the bolt holding the two halves together nearest the brake line and bleeder is completely stuck and the head is pretty damn stripped out. So far I've only managed to make it worse. Suggestions?

Heat, drive a torx bit into what's left of the hole, and use a hand held impact driver.


or, weld a nut to it...

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Or you could drill off the head. Once it's apart, You could work it out with vice grips.

Remove the other bolt and clamp the threaded half of the caliper in your vices soft-jaws. With a plastic mallet, whack the bolted half so as to loosen the caliper half and bolt. PB won't hurt, either.

Rebuild kit usually has piston dust seal x 2, piston wiper ring x 2, small o-ring x 2, new bolts, a small tube Brembo rubber grease.

Have a look here. It should help some.

This ended up working great.

Looks like someone had a hard time getting the pistons out in the past, they're all gouged up on from someone trying to pry on them. Popped right out (and shot across the garage) with a little air and look pretty clean with the exception of the gouges.

The lip on the piston helps seat the dust seal, so if you can tidy them up they might still be fine.
