ABSTRACT:
A vehicle braking system wherein, for avoiding serious brake unbalance under fault conditions which would cause either loss of braking or excessive braking at one wheel, a small bore link pipe is arranged to connect the pressure control elements, for example solenoid actuated relay valves, of respective brake circuits associated with the two wheels at opposite ends of an axle whereby the pressure control elements in each electronically controlled pressure adjustment channel are influenced in such a manner that a correctly functioning channel attempts to influence a faulty channel in such a direction as to reduce the pressure unbalance.
