Re: New Member - Help with disassembly of Power Brake Unit

Brian mentioned the Compensator Port Valve and spring. THAT IS the issue i have with the TV master cylinder. If the tiny spring fails then there will be NO brakes.
More common variety of master cylinders, wheather dual or single, can fail too but will usualy give some adequate warning and allow for pumping of the brake pedal to over come the failure. If the spring, or any part of the Compensator valve in the Treadle Vac master cylinder fails then it is NO brakes at all and no interveneing warnings.
Other than the Compensator Port Valve i have no complaints with the TV system. BUT, the Compensator Port is a MAJOR issue.
