Abstract
A hydraulic brake control assembly for a vehicle having a master cylinder and a brake wheel cylinder including a housing having an inlet port which is in communication with a master cylinder and an outlet port which is in communication with a brake wheel cylinder, a proportioning valve positioned within said housing and which includes a slidable valve piston for effecting proportioning operation, a plunger positioned within the housing and coaxial with the valve piston, a first spring positioned between the valve piston and the plunger for biasing the valve piston in a direction wherein the proportioning valve is positioned in an open position, the housing including a first chamber formed therein in communication with an inlet port and in communication with the outlet port by way of the proportioning valve and a second chamber communication with the inlet port, the valve piston having an effective pressure receiving area which is exposed to the hydraulic fluid within the first chamber so that the valve piston is urged against the first spring, the plunger having an effective pressure receiving area which is exposed to the hydraulic fluid within the second chamber so that the plunger is urged in a direction in which the first spring is compressed and a G-valve positioned between the inlet port and the second chamber within the housing for interrupting fluid communication therebetween in response to a preset deceleration of the vehicle.
