ABSTRACT:
A hydraulic anti-lock braking system incorporates a pump for generating the energy necessary to re-apply a brake automatically after pressure applied to the brake from a master cylinder has first been released to prevent the wheel controlled by that brake from locking. The pump is adapted to pump fluid back both to the brake and to the master cylinder. Pumping the fluid back to the brake achieves a satisfactory pedal feel, and pumping fluid back to the master cylinder ensures the use of a fail-safe re-application of brake pressure.
