A brake control mechanism (14) includes a housing (20) with a stepped bore (22). A valve member (44) cooperates with a seat (46) to close communication from a master cylinder (10) to a brake assembly (12) when a vehicle is going up a hill. An actuator assembly (78) is operatively coupled to a clutch assembly (16) and is comprised of a plate (50) to control operation of the valve assembly in response to actuation of the clutch assembly (16). The plate (50) includes a relatively small axial dimension and forms a central opening (54) for receiving the valve member (44).
