<p>: A brake control device for preventing backward movement of a vehicle on an uphill road during operation of the clutch pedal after release of the brake pedal, the device including a cylinder body having iol passages for connection between the master cylinder and the wheel cylinders of the vehicle. A spring biased hollow plunger is reciprocably received within the cylinder body to provide flow communication between the oil passages in a first position thereof when the brake pedal is actuated, and to prevent the oil from returning from the wheel cylinders in a second position thereof when the clutch pedal is actuated upon release of the brake pedal. An electromagnetic switch-activated system moves the hollow plunger from the first position to the second position when the clutch pedal is actuated. A second oil path is provided in the cylinder body to supply additional oil from the master cylinder to the wheel cylinders when the hollow plunger is in the second position and the brake pedal is reactuated for an increased braking force.</p> |
