Digging up an old thread with new info for my first post:
I've been researching what it takes to rebuild these valves for the last few years. I just finished doing an autopsy and rebuild on a valve that I think was used on several different 1968 - 1970 Mopars. Does yours look like the one in the attached picture?
There are two tricky things about rebuilding these valves:
- Using the right material. EPDM is the best rubber compound for seals that are exposed to brake fluid. The typical o-rings you can get at a parts house made from Nitrile/Buna-N are NOT compatible with brake fluid!
- Sourcing the special seals that aren't o-rings. I've had them custom made.
I've been reading up on forum policies towards linking to other sites, but I'm not sure if it's OK to provide links to my work since I use my site to sell parts and publish technical information. Is it OK to post links?
