Abstract

An inertia-controlled valve unit for limiting the pressure rise in the rear wheel circuit of a vehicle hydraulic braking system is by-passed when the front wheel circuit fails, so as to give full braking pressure in the rear wheel circuit. The valve unit has an outlet 34 connected to the rear wheel brakes, and an inertia-controlled valve 3, which closes when the deceleration of the vehicle is excessive, to ensure by means of a metering valve 20 that any subsequent increase in pressure applied at the outlet 34 occurs at a rate less than the rate at which the master cylinder pressure increases. The unit also incorporates an override means 13 responsive to front wheel brake pressure which is operative, following closure of the inertia-controlled valve 3 and reduction in front wheel brake pressure, to override the effect of the inertia-controlled valve 3. <IMAGE>
