The Stovebolt Site Forums The Parking Lot Big Bolts Unusual Brake Issues on 1956 Chevrolet 6400

Chevy's till I d, the master cylinders aren't showing signs of leaking at all anymore now that most have been replaced or serviced.

Justhorsenround, I have the manual and will follow that procedure. I did it a few days ago, but I forgot to use the pneumatic bleeder on the hydrovac. I suppose that could have left some air in the system and caused problems.

BlackViking60, thank you! I will follow that again and use the pneumatic bleeder on all of them. I do need to upgrade a few of the bleeder valves though first.

sweepleader, I adjusted the passenger's side rear shoes down because the top shoe wasn't even touching the rod coming out of the rear cylinder (then I realized it was because the shoe was hung on something) and when reinstalling the drum, it slid on quite easily. The others are good and dragging a little (the only drum I haven't taken off is the driver's side rear... mainly because it took us two hours to break the lugs on the passenger's side with heat, but also because it's not showing signs of any issues). Would one loose side of shoes be enough to get it to hold pressure in the master cylinder only for 5 to 10 seconds and then cause it to lose all pressure?
