Abstract
A fluid operated braking system for a motor vehicle, having a main braking circuit for applying braking pressure to the actuators of both wheels of at least one axle of the vehicle, and a subsidiary braking circuit for applying a reduced braking pressure to one of the wheels of the axle if it should enter a skid or incipient skid state, in which the subsidiary braking circuit is controlled by two distributors each of which is associated with a respective wheel and has three ports, one connected to the main braking circuit, one connected to the subsidiary braking circuit, and one connected to the brake actuator of the associated wheel of the axle, the distributor being controlled by an electrovalve to connect the main braking pressure circuit to the brake actuator of the associated wheel of the axle under normal braking conditions, and to connect the subsidiary braking circuit, through an internal path within the distributor, to the brake actuator of the associated wheel of the axle if this wheel enters a skid or incipient skid state, without affecting the distributor associated with the other wheel of the axle.
