The improved release mechanism comprises a load sensor (50, 51, 150, 250, 350, 450) connected with a wheel brake (10, 110) to sense a change in wheel braking torque and communicate responsively with a mechanical brake control device (200) or a braking assistance servo-motor system (310, 320; 410, 420) which releases the brakes when the vehicle commences acceleration along an incline.
