ABSTRACT:
A rear brake pressure proportioning control device is disclosed, with a regulating piston (7) and with a valve closing member (9) being supported within a slidable control piston (8), the movement of the control piston interrupted at a predetermined rate of vehicle deceleration. A restriction (32) between the inlet and inlet chamber within which the control piston is disposed prevents a high rate of brake pressure increase from causing too high a rear brake pressure. A multiple-stage restrictor (26) is positioned in the inlet in order to prevent a very high rate of pressure increase of the brake pressure resulting in too low a rear brake pressure.
