Abstract
A pendulum responsive to excessive deceleration operates a valve which creates a pressure differential across a pressure responsive member to close an inlet valve to the brake chamber and expand an outlet chamber to thereby reduce the rear brake pressure. The invention provides retaining mechanism for preventing the pendulum from swinging during non-braking periods and for returning the pendulum to its inoperative position upon a reduction of inlet pressure. A piston responsive to pressure at the inlet moves the retaining mechanism to a position wherein the inertia member is free to swing during normal brake applications.
