Abstract
In a combined booster and hydraulic master cylinder assembly the reservoir connection is adapted to serve as an inlet for high pressure fluid and by way of which the assembly can be operated independently of the pedal. High pressure fluid is supplied to the connection under the control of auxiliary control valve responsive to signals for a sensor. The sensor may be arranged to enable the assembly to be used in a variety of modes, for example for traction control, as a `hill holder`, and for remote control of the speed of the vehicle.
