Stuck Brake Pedal

Posted by RP On 2014/3/27 21:47:00

Looking for some advice. I'm new to your forum since December. I have a '53 Convertible that thanks to the Kantar brothers, has new axle seals, pinion seal, brake cylinders, shoes, parking brake cable, water pump, thermostat, voltage regulator, shocks, turn signals, heater hoses, heater ducts, u joints, rebuilt generator, and radiator serviced.
Solved slipping trans with "F" type fluid, 1/2 quart of Lucas "snot", and 9 turns in till 20 ft#s and 1 3/4 back out on low band.
Can any one tell me why my brake pedal sticks half way down after being applied? It will put you through the dash. But then the brakes stay held until you hear a release of fluid or vacuum. It's a weird noise. To me it sounds like air or vacuum trapped for about 3 seconds am
And then the noise, the pedal bounces back up, and off I go.
Could it be not enough vacuum?
The tank on fender well holds vacuum off the manifold.
Could it be a bad "check valve"on the booster?
Could it be a collapsing brake line that is slow to return to form?
The symptom was there prior to all the brake parts replaced
This is my last issue to be solved in order to make it into an everyday driver.
Thanks, RP
