<p>@ A brake apparatus (10) having a master cylinder (16) with a flange (24) connected to a first shell (56) of a booster (18) and a stationary firewall (71) of a vehicle. A first wall (70) located between the flange (24) and first shell is connected to a piston (38) in the master cylinder (14). A second wall (144) located between the first shell (56), flange (24) and a second shell (121) is linked to the first wall (70) by a plurality of bolts (180) that pass through the flange (24). A valve (102) in response to an input controls the development of a pressure differential across the first and second walls (70) and (144). This pressure differential creates a force such that the first wall (70) pushes piston (38) while the second wall (144) pulls the first wall (70) to pressurize fluid in the master cylinder (16). Since the flange (24) fixes the master cylinder (16) to a stationary firewall (71), measurable axial deflection is eliminated and the entire input is used to operate valve (102) and effect a brake application.</p> |
