Abstract: A self adjusting parking brake system which automatically removes slack from a parking brake cable includes a fixed support and a hand-operated lever pivotably connected to the support for movement between brake-releasing and brake-engaging positions. A locking mechanism releasably maintains the lever in the brake-engaging position. The locking mechanism includes a main ratchet having a plurality of ratchet teeth and a main pawl having a pawl tooth engaging the plurality of ratchet teeth. A self-adjust mechanism connects the cable with the lever. The self-adjust mechanism includes an adjuster ratchet having a plurality of ratchet teeth and an adjuster pawl having a plurality pawl teeth. Only one of the plurality of pawl teeth fully engages the ratchet teeth at any one time. The adjuster pawl pivots about a pivot axis and has an approach angle of greater than forty-five degrees.
