The electro-hydraulic brake proportioning valve on my 1992 Ford Ranger leaks at what looks like a vent hole on the plug? at the rear of the valve. Does this valve have o-rings or parts that can be replaced or should I just replace the valve? Thanks for any help Glen
Replace the valve, flush brake system first.

Why flush it first? If there is a problem with something coming apart in the valve block you dont want to take a chance it could be washed out into the system. I mean what is there, is there, but why add anymore to it, or take that chance? I would suggest to flush the system after replacing the valve block.
