ABSTRACT:
A brake master cylinder assembly comprising a cylinder body having a stepped axial bore with large and small diameter portions, a tubular piston slidably disposed in the large diameter portion, and a primary piston one end being slidably disposed in the tubular piston and the other end in the small diameter portion, the primary piston being operatively connected to the brake pedal. The other end of the primary piston defines a pressure chamber in the small diameter portion in communication with the brakes. The primary and tubular pistons define an annular pressure chamber in the large diameter portion. Actuator means indirectly responsive to movement of the brake pedal moves the tubular piston to create low pressure in the annular pressure chamber which is in restricted fluid communication with the pressure chamber providing braking pressure at idle with reduced force on the brake pedal required.
