disc brake prop. valve. maybe..
does anyone know if it could be a disc brake proportioning valve problem? mines leaking and before i replaced my master cylinder my rear brakes kept locking up when i applied the brakes.. it just started happening and all my brake fluid leaks all the way out. i didnt even know anything about the disc brake proportioning valve until i saw where it was leaking and looked it up, oh , and its leaking at the top where a plug/vent is, i took that out and there is a spring backing it.. well, i guess my question is, is that something i can fix w/o replacing the whole thing($230.00+).. probably not the same thing ya'll are talking about and i should of posted a new thread, but i thought i ask.. 91 TEXplorer
