Patent ID: 7010411

Claim:
A pump-less anti-lock brake apparatus for controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front and one rear wheel and front and rear brakes acting on the front and rear wheels respectively, the apparatus comprising: a rear brake hydraulic circuit including a master cylinder for supplying a volume of pressurized brake fluid to the rear brakes during the braking cycle, a fluid storage element, and a rear brake pressure control (RPC) apparatus; the RPC apparatus including a hydraulic control unit (HCU) and an electrical control unit (ECU), with the HCU operatively connecting the master cylinder to the rear brakes and the fluid storage element for controlling fluid pressure applied to the rear brakes during the braking cycle and fluid flow to the fluid storage element, and the ECU operatively connected to the HCU for controlling the HCU as a function of the rotational speeds of the at least one front and one rear wheel.
