ABSTRACT:
A hydraulic brake assembly with pneumatic power assist has a master cylinder inserted in a housing in turn at least partially surrounded by an annular power-booster device comprising a pair of annular chambers divided by a membrane. The membrane is connected via a plate and a sleeve or tie rods to a tension rod axially traversing a substantial portion of the master cylinder. The tension rod engages an actuator piston placed in compression by a push rod upon the actuation of a brake pedal linked thereto. The force for actuating a fluid-compression piston in the master cylinder is thus transmitted thereto partly via tension-stressed elements and partly via compression-stressed elements. Force feedback to the brake pedal is implemented either hydraulically via fluid-flow channels in the tension rod or mechanically via a lever inside or outside the housing. A fluid reservoir is removably mounted on the housing in juxtaposition to the booster chambers and transversely to the housing axis.
