I know they are not that expensive and are pretty easy to replace, bu I was just was wondering if anyone has ever tried rebuilding the clutch slave/master cylinders. Thanks!

 

It can be done. It's just more and more of a pain to find the parts. Manufacturers of parts want to carry one assembly with a larger profit margin. Not one assembly, one slave, one master, 4 or 5 different o-rings etc.

Pull yours apart, measure the o-rings, find the right o-rings for brake fluid usage, buy them, put it all back together and let us know how much time you invested, and where you located the parts.
