Abstract
In an hydraulic anti-lock braking system a modulator incorporates a valve responsive to anti-lock signals, a flow valve, and an expansion chamber to which fluid is relieved from a brake in an anti-lock mode. The flow valve is arranged so that the output from a pump is shared between the brake and the master cylinder, and a restrictor located in parallel with the flow valve is adapted to attenuate the pressure oscillations of the system.
