ABSTRACT:
The control apparatus comprises a housing having first and second hydraulic pressure chambers formed therein and communicated to each other through a communication passage. The first hydraulic pressure chamber is hydraulically communicated with a master cylinder actuated by a brake pedal of the vehicle, while the second chamber is hydraulically communicated with the rear wheel brake cylinders. A differential piston is axially movably disposed within the housing and having one end portion exposed to the first hydraulic pressure chamber and the other end portion projecting into the second hydraulic pressure chamber. The effective area of the differential piston subjected to the hydraulic pressure is made smaller at the one end portion thereof located in the first pressure chamber than at the other end portion located in the second pressure chamber by forming a sealed air chamber adjacent to the first pressure chamber between the inner wall of the differential piston and a stationary sleeve on which the piston is movably supported. An inertia valve member is disposed in the first hydraulic pressure chamber and adapted to close the communication passage when deceleration of the vehicle attains a predetermined value.
