<p>The cut-in point of a brake pressure control valve (4), suitably an apportioning valve or a cut-off valve, is adapted to be determined by the deceleration of the vehicle, and the input pressure. These parameters are sensed by suitable sensors (15, 16). The cut-in point is recognised by an electronic control unit (18) which receives signals from the sensors (15, 16) and, at that point, is operative to energise a solenoid-operated valve (20) which prevents any further direct increase in the pressure applied to the rear brakes (3) from a master cylinder (1).</p> |
