ABSTRACT:
A parking brake actuating and release mechanism actuated through a series of strokes of the brake pedal lever to tension the parking brake cable throughout the desired range, the parking brake cable being connected with an eccentric cable take-up member so that the effective leverage applied to the cable causes the mechanical advantage to increase through at least the predominant range of actuation of the mechanism. A release mechanism provides quick release of the parking brake so that it returns to the released position.
