clutch & brake master cylinder rebuild

Postby biker_guy » Mon Mar 28, 2011 4:38 pm



I was looking at the front brake master cylinder how to. Is the clutch master cylinder rebuild the same only on the opposite side? Also I've been looking all over and is the clutch and brake master cylinder parts the same? Like if I put in an order for 2 brake master cylinder rebuild kits will it fit the clutch as well? They both are leaking and I can only find either or on a site so it would save shipping if I could double the order and order from one place.

I had a look, and the only part in the OEM parts fiche that is common between the two is the rubber boot that fits over the whole assembly. Even the internal circlip is different, which leads me to believe that the internal master cylinder bore diameter is different - which would make sense, as the brake master cylinder has to move a lot more fluid (multiple large volume pistons) than the clutch master (single small volume piston). So I suspect your plan of duplicating parts won't work.

Ok thanks! I'm glad I waited for your response. I found different sites that had either part listed as the same number. I'll have to keep an eye out for that.
