I have read alot of threads on here and still haven't seen anything that has helped. Here is what i got I have a 1952 Chevy car with a complete Walton fab brake booster set up and master cylinder. I have a disc brake kit put on the front and a s10 rear end in the rear. I am trying to bleed the whole system but all i can get is a mushy pedal. If i pump the brakes about 4 times they stick tight but just once to the floor i can still spin them. I have bench bleed the master and got alot of air out that way, i have full fluid with no air coming out of all the bleeder screws, no more leaks everything is tight. The master is on the firewall. I have no valves of any sort inline here. I have bleed lines before but dang never had a problem like this. the front line was a tad long so i had to bend a few zzzz's in it to get it to fit i hate double flaring. I could swear i have enough stroke in the pedal also. I don't want to damage the master by pushing it in to far. let me know what everyone else thinks on this. I would hate to have to pay someone to fix this when i am sure i have over looked something. Thanks everyone for anything you can offer!!!
