Having terrible time with the early hydraulic brakes on my 26 Chrysler mod 50 touring car. I've completely rebuilt all components, replaced all lines and had m.cylindr professionally sleeved. I even rigged up a pressure bleeder to bleed the system but every few months or so, the whole pedal starts hitting the floor boards again.I noticed the master cylinder doesn't contain any other components but the piston and cup. Seems strange.Haven't found any leakage anywhere. Never get a really good pedal even after pressure bleeding. Have installed a turn off petcock in line to reservoir can on firewall otherwise totally impossible to bleed as m.cylinder backs up into reservoir can instead of pushing to wheel cylinders. Any help greatly appreciated.Yes, the air hole in cylinder is clear.
