ABSTRACT:
A brake booster (10, 210) connected to a control circuit (120) provides a system for the continued braking of a vehicle when the vehicle is situated on an incline and the brake pedal (92) is released by the operator. Continued brake application is accomplished by utilizing a control circuit (120) responsive to vehicular attitude, clutch pedal position, and vehicular direction. The control circuit (120) is connected to the combination of a check valve and two-way solenoid valve (100, 200) connected to a movable wall brake booster (10, 210). The combination valve (100) is connected to a flexible hose (110) disposed interiorily of the booster (10), and the other end of the flexible hose (110) connected to the input opening (32) of a three-way poppet valve (70) located at the central hub (30) of the booster (10). When the control circuit (120) senses that the vehicle is on an incline, the clutch pedal depressed, the ignition "on", and the vehicle not backing up, it actuates the two-way solenoid of valve (100) which continues to supply a first fluid pressure to the front booster chamber (40) while closing to prevent the supply of the first fluid pressure to the rear booster chamber (50) via the flexible hose (110) and poppet valve (70). The vehicle operator may release the brake pedal (92) which returns slightly toward an inactive position and which opens slightly valve (70), with the brakes remaining activated because the second fluid pressure is maintained in the rear chamber (50) by the closed valve (100) so that the second fluid pressure may not escape via hose and connection (110) and valve (70), and thereby maintaining the axially displaced position of the movable wall (24).
