Rebuild, or buy a new one???

[nsarvai]

I have a 1994 BMW K75, that I took out of storage this year, had to rebuild that caliber in the rear. I did all that smoothly then bleed the brakes. When doing this I came across a lead that I didn't know about. The master cylinder seal is leaking. After taking it for a ride the brakes hold up fine, but still leaks. I have been looking at parts and would like input. Should I get a rebuild kit for $90, or should I buy a new master cylinder for $250?

Rebuild kit should be all you need since you report the brake is working but leaks.

Thanks,
I am going to try that... Will post back to see if all works well.

You may be able to open it up and clean it up real good to cure it......
I had my front MC not building pressure, though it wasn't leaking.
Pulled the piston out, cleaned the bore, honed it, re-assembled and all is well. Builds pressure good and firm, no leaks.

I just ordered the rebuild kit online! I will have to take it apart and check that out before I use the lot! I just want to get out riding again! Had to take my R60 out for a spin instead today! Thanks again for the help!

Where'd you buy the kit, Nic?

I get most of my parts from MAX BMW Motorcycles!

They are the same price as the BMW store online, but figured it's a lot closer to home for shipping! Anywhere I looked it was the same price!
