RE: Brake problems

[Errol Smith]

Title: Message

Heath, The check valve is fitted to the master cylinder to keep a 2-3 psi residual pressure in the rear drum brake line so the shoes do retract fully after operation. With a disc brake this means the pads may not fully release, Another item to check is thaaat the pedal is allowing the piston to fully open the bypass port so residual pressure is being released from all line. If the travel is not sufficient for the piston to open the transfer port of the cylinder you will not get a pressure drop in the line so thew pedal is hard from the strat of application.
