Abstract
In a hydraulic brake system which combines a spring actuated, hydraulically released parking brake system with a hydraulically actuated service brake system and in which the parking and service brake systems both operate through a common force-transmitting element on the brakes, and in which the fluids in the two brake systems are mutually incompatible, an anti-compounding valve limits the sum of the forces which can be transmitted by the common force-transmitting element when the service and parking brake systems are simultaneously applied and which maintains the fluid in the two brake systems isolated from each other.
