Title: master cylinder rebuild kit
Post by: fabioblazer on April 29, 2009, 12:10:51 pm

hi guys!
i have a Reybestos master cylinder rebuild kit (precisly: Raybestos MK1737), but i have a doubt about the 3 seals inside the package.
2 of them are similar, the other one is different but before keep out master cylinder, i'd like to know where i must to install them.

i don't know if i must use them to replace old seals on the secondary piston or i must install them between reservoir assembly and master cylinder.

surely i could remove master cylinder and check out the correct position, but maybe it's better to know before  ???

someone can help me please?
thanks
Fabio

i would just replace the whole master cylinder, its easier and should be pretty cheap

Never had much luck with rebuilt, even the store bought ones. I got a rebuilt one from a chain store with lifetime warranty, lasted 3 months, replace it and it lasted 2 months. Bought a new one from NAPA and it lasted 15 years.
