ABSTRACT:
A foot-operated parking brake lever assembly wherein a double-manual operation is required to effect release of the parking brake. The assembly is provided with a pawl having a first pawl section and a second pawl section. The first pawl section is pivotally mounted on a brake lever which is in turn pivotally mounted on a stationary support formed with a series of ratchet teeth. The first pawl section is formed with a finger for selectively engaging the ratchet teeth and thereby retaining the brake lever in brake setting positions thereof. The second pawl section is mounted on the first pawl section for limited rotational movement therewith. The second pawl section is urged by pawl biasing means in a direction to cause the finger of the first pawl section to engage the ratchet teeth when the second pawl section is in a rotational position subject to the limiting action by limiting means and in a direction to cause the ratchet teeth of the first pawl section to be disengaged from the ratchet teeth when the second pawl section is in a rotational position free from the limiting action by the limiting means. Brake lever biasing means urges the finger of the first pawl section in a direction to engage the ratchet teeth.
