ABSTRACT:
A vehicular anti-lock and traction control braking system includes a master cylinder. A driven wheel brake is connected to the master cylinder via a first brake conduit. A non-driven wheel brake is connected to the master cylinder via a second brake conduit. A fluid supply is connected to an input of a pump. An output of the pump provides pressurized fluid to the driven and non-driven wheel brakes. A pump supply valve is disposed between the pump inlet and the fluid supply. A driven wheel isolation valve is disposed in the first brake conduit between the driven wheel brake and the master cylinder. The driven wheel isolation valve is opened to allow fluid communication between driven wheel brake and the master cylinder and closed to prevent fluid communication therebetween. A non-driven wheel isolation valve is disposed in the second brake conduit between the non-driven wheel brake and the master cylinder. The non-driven wheel isolation valve is opened to allow fluid communication between the non-driven wheel brake and the master cylinder and closed to prevent fluid communication therebetween. During a traction control event, the non-driven wheel isolation valve is opened to provide a circular fluid path from the pump output through the non-driven wheel isolation valve to the pump inlet.
