Re: Leaking Brake Fluid

Where exactly is it leaking from? Pics would help alot. Your master cylinder is probably alright, as long as the brake fluid you're seeing isn't running down the lines from the master cylinder and dripping off the prop valve. Is it leaking from the fittings, or somewhere else?

Junkyard one should be fine. Proportioning valves very rarely go bad. Are you sure its the valve itself and not the lines? It's not leaking around the threads is it? Just want to make sure you avoid as many headaches as possible.

Oh ok. I didn't see where/if you mentioned where the leak actually was coming from. In that case, I'd just hit the local junkyard and grab one.
