Abstract
A brake system contains a safety mechanism which terminates an automatic brake upon detecting that unnecessary braking force is developed as a result of a failure in an automatic brake controller. In the event a braking output is developed when neither a brake pedal nor the automatic brake controller is operated, the safety mechanism determines the occurrence of an abnormality, and interrupts a communication between the master cylinder and the wheel cylinder while decompressing the oil pressure in the wheel cylinder by discharging it into a low pressure accumulator. The safety mechanism allows the automatic braking to be terminated, thus allowing a risk of a collision by a succeeding vehicle to be avoided and allowing a vehicle to continue running.
