‘66 Barracuda Brakes Suck — Proportioning Valve Maybe?
Formula S, KH discs front, 10” drums rear. Brakes were decent when I bought this car. While going through much of the car, I converted the single pot MC to a new (not rebuilt) dual pot 15/16”. The car does not stop well, no confidence if I have to make a panic stop.
Ever since then, I have a brake pedal that has normal travel, but then gets real hard. I’ve checked the calipers. They’re free. I’ve checked the rear brakes and compared to the factory service manual, all springs and adjusters are correct. I’ve rechecked my brake tube routings. I have slack in my parking brake.
My best guess is this old Kelsey Hayes proportioning valve may not be functioning or stuck. I’ve attached an image I found on the internet and two pictures of mine. I’m open to ideas and suggestions...
