I have a 65 ElCamino with manual drum brakes all around. I replaced all shoes and wheel cylinders, rear axle seals which were leaking, adjusted shoes to just drag, bled system 5 times now, and I still have a hard pedal to push and they barely stop the car. I realize I'm spoiled by power brakes, but somethings not right. Any ideas other than converting to power or disc brakes? Thanks, Crash.
