Red face BRAKE PROPORTIONING VALVE Problem

I have a 77 F-150 PO had put a bolt on valve where switch was I got a new switch and found out why the bolt was there it leaks fluid out around switch I don't think fluid is supposed to be there inside seal is gone. I guess I need to replace valve . Does anyone know where to get a stock one or should I do the pull apart thing or maybe a after market thats adjustable from summit.

IIRC, a replacement is like $250 or something like that. I'd go with an adjustable unit (Wilwood, SSBC, MP Brakes, etc) if mine failed. Get one with the provision for the brake warning light or else that light will be on and staring at you all the time. An alternative is leave it unplugged but that's kinda hackish IMO.

As to the original problem, you got it right. Bolt in that hole was to seal it up, and the fact that there was fluid in there at all means it was bad.

I have the bolt right now, works for me but whatever suits your build.
