Hi all. Last week I installed front disk brakes on my 57 Plymouth Now I am having trouble getting the brakes to work. Does any one know if the proportioning valve from a power brake car will work on a Manuel brake system. My pedal feels like it still has air in it I have bled the system numerous times and still the pedal is spongy. I have put on a front disk kit from aajinc. A rebuilt duel master cylinder for a 70 duster. The brass proportioning valve off a 68 Imperial this is the one that separates the front from the back brakes I think that's what they call the proportioning valve. I have put on new brake lines too. Thank you for any help. Bob. bobsmopar@xxxxxxxxxxxxxx |
