Abstract
A fluid pressure braking system includes a pair of service reservoirs which supply fluid pressure to the system dual brake valve for actuating the vehicle service brakes. The reservoirs, through appropriate valving, also operate a third brake circuit which controls the vehicle parking/emergency brakes, thereby eliminating a reservoir for the third system, which was necessary in prior art braking systems.
