So here is my situation and I am not sure what to do next. I have a 1969 Sport Satellite, originally manual drums, now factory 1970 b body 11” discs up front and factory 10” drums on rear. I installed a Pirate Jack’s power booster and drum/disc master cylinder and a correct proportioning valve. At first, the pedal would sink to the floor. I could never get the rear circuit to bench bleed correctly. I replaced with a Raybestos MC and brakes feel great and I can easily lock up the 245 wheels up front. The problem is, every so often, the brake pedal will stay depressed and not spring back like it should. Next 3 traffic lights it works great, then decides to stay depressed. Linkages are all clean and lubed, no brake fluid leaks anywhere. The system has been bled numerous times. I took it to a local speed shop, they had it for two weeks and were stumped as well. Any ideas? Where do I look next?
