Abstract
A parking brake system for motor vehicle air brakes provides automatic engagement of the parking brakes when a gearshift lever is moved to park, but requires manual disengagement of the parking brakes. The effect is achieved in part by controlling the discharge conditions of two piloted latch valves connected to feed air to a cab mounted push pull double check valve.
