Abstract

A brake system having a combined electrically operable demand signal control valve and emergency valve (50) comprising a first inlet connected to the supply line (16), a second inlet connected to the reservoir (14), and an outlet (45) connectable to the fluid pressure brake operating signal inlet of the supply valve means (40), a valve member to control flow of fluid pressure between the second inlet and the outlet and said valve member being movable by electrical means (21) responsive to said presence or absence of electrical supply to the system and by fluid pressure means responsive to said pressure in the supply falling below said predetermined value.
