A parking brake actuator includes a support bracket, a lever supported by the support bracket and pivotable between a brake-released position and a brake-applied position, a push-to-release lock mechanism operably connecting the lever and the support bracket to selectively lock the lever in the brake-applied position, and a self adjust mechanism having a cable connection and a sector member pivotable relative to the lever, a spring member resiliently biasing the cable connection in one direction, and a pawl secured to the lever and movable between a first position wherein the pawl engages the sector member to prevent pivoting motion of the cable connection relative to the lever and a second position wherein the pawl releases the sector member. The pawl is resiliently biased to the first position and the pawl engages an abutment when the lever is in the brake-released position to move the pawl to the second position.
