Abstract
A braking system for a vehicle, having a transducer capable of responding to a fluid pressure brake demand signal to provide an electrical brake demand signal to an electronic control means which is responsive to the electrical brake demand signal to provide an electrical brake operating signal. The electrical brake operating signal is supplied to an electrically operable valve means which is arranged to supply a fluid pressure brake operating signal from a source of fluid under pressure to control a supply valve which supplied fluid from the source to at least one actuator for brake application under a brake pressure determined in accordance with the electrical brake operating signal. An electrically operable fluid pressure brake demand signal control valve controls the supply of the fluid pressure brake demand signal to the supply valve as a substitute for the fluid pressure brake operating signal originating from the source.
