I was driving the car before putting it away for the winter and about an hour away from the house when I applied the brakes ( power drum brakes, auto trans) the pedal would stay where ever I pushed it to, half way, 3/4 ect, but the pedal would not return and the brakes would stay engaged until lifting the back up . I had to put my foot under the back side of the pedal to lift it back up. Had to do this all the way home. I did not lose any fluid, so there was no leak anywhere and I also checked the fluid in the master cyl....all good there. I thought it might be the master cyl itself so I replaced it and still had the same problem. There is no return spring on the pedal, so that's not it. I was thinking the power booster maybe was bad. I took off the vac. line coming from the intake to the booster and there was plenty vac going to the booster ( 20 inches of vac). Once the vac line is off the engine revs up a few 100 rpm....that's normal, when I hook it back up the rpm comes back down to normal, so good so far.
I figure that if the booster is leaking the engine should act like it has a vac leak and have higher RPM's.
So, I am not sure what could be wrong, Check Valve? something else? Any ideas?
I have the Midland Ross type booster with the white check valve and 2 nipples on it, one bigger and 1 smaller.
Why would my pedal not come back up each time? Stumped.....
