ABSTRACT:
A proportioning valve in a master cylinder is pressure responsive to control the flow of fluid to a wheel cylinder. An inertia sensing member is responsive to the deceleration of a vehicle and is operatively connected to the proportioning valve to control the operation thereof. The inertia sensing member defines a neutral position relative to a housing supporting the proportioning valve. During braking the inertia sensing member generates a force biasing the inertia sensing member toward the proportioning valve, but remains in the neutral position to oppose actuation of the proportioning valve. The proportioning valve includes a sleeve and a pilot which extends through the sleeve to engage the inertia sensing member.
