Abstract
A vehicle braking system has a controller responsive to wheel speed signals for sensing skid conditions of the wheels and for generating skid control instructions. A primary fluid pressure supply includes a fluid pressure source and a fluid pressure reservoir and wheel brakes are responsive to brake pressure supplied to the brakes by supply valves, each of which is adapted to supply fluid brake pressure to a different wheel brake or brakes from the primary supply in accordance with a brake operating signal which can be modulated by skid control units. Each pair of supply valve and skid control unit is adapted to control the fluid pressure of a different wheel brake or brakes. A plurality of brake operating signals are generated, independently of the skid control units, as a function of a brake command signal and a brake operating signal is supplied for each of the supply valves. All the components are connected together so as to be mountable on the vehicle as a discrete unit.
