Claim:
1. A park brake assembly comprising: a base; a park brake lever pivotal about the base; a pawl pivotal about a pawl pivot, the pawl linked to the brake lever; a mounting bracket attached to the brake lever and rotatable about a pivot pin attached to the base; a sector attached to the base, the pawl releasably locking and unlocking relative to the sector; the brake lever including a rod connected to an actuator for actuating the park brake assembly and a spring member contacting the pawl at one end of the spring member and contacting the mounting bracket at another end of the spring member biasing the actuator and biasing the pawl about the pawl pivot and into engagement with the sector; wherein the pawl includes a pivot slot that receives the pawl pivot and wherein the pawl translates about the pawl pivot changing a contact of the pawl relative to the sector when the sector exerts a force upon the pawl when there is a friction force between the pawl and sector preventing the pawl from entering the sector.
