Summary:Abstract of Disclosure A releasable brake pedal system 10 for a vehicle includes a pedal assembly 12 operatively engageable by the driver of the vehicle and a hydraulic actuator assembly 20 for generating pressurized hydraulic fluid for actuating one or more brakes 44A-44D. The pedal system 10 further includes a pressure release valve 30 or 30´ coupled in fluid communication with the pressurized hydraulic fluid. The pressure release valve 30 or 30´ is operative to reduce the amount of pressure applied to the brakes 44A-44D during a detected vehicle deceleration indicative of a collision event. The pressure release valve 30 is responsive to a deceleration sensor 40 according to one embodiment, and valve 30´ employs a deceleration sensitive inertial mass 76 according to another embodiment. Accordingly, the pedal system 10 reduces forces that may otherwise be transferred to the pedal assembly 12 during a collision.
