Hi, hoping to hear from someone else who has been thru this. came out one morning, no brakes pedal on the floor. found no leaks. since it was all original, started to rebuild. master had very dirty rusty fluid in it. cleaned, honed rebuild kit, seems to work normally. metering valve that hangs on the stud, cleaned, seems to work normally. didn't find a rebuild kit for that. dist block on the frame soaked, cleaned, seems to work normally. blew air thru all of them. new steel front brake lines. cleaned out system with denatured alcohol and used Dot5 fluid. fluid leaks from all 4 screws if opened. when I took off the calipers there was a piston stuck on each side. tapped on it and they all seem to move well. did not rebuild them at this time.

at this point, if the car is off, the pedal almost can not be pushed down. if the car is on, pedal goes to the floor. am assuming the switch in the dist block is working as the idiot light comes on when pedal hits the floor. realized the only thing that hadn't been touched was the booster. when the car is on, and pedal pressed, it does sound like air is escaping somewhere. I thought I always had that noise so I never thought of it. the vacuum line from the back of the carb seems normal.

at the moment I assume I need a new booster. would request ideas and suggestions as to what I might have missed before buying one. can a booster be tested? thanks for your time.
