ABSTRACT:
An improved parking brake cable control apparatus includes an automatic cable tensioning device that is operable at the beginning and end of every parking brake operating cycle to take up cable slack and maintain uniform cable tension. The foot-operated parking brake lever pivots on a main pivot shaft between brake-engaged and brake-released positions, a releasable pedal pawl being provided that cooperates with a conventional pedal ratchet. A cable-tensioning ratchet connected with the parking brake cable is rotatably mounted on the main pivot shaft, and cooperating therewith are a lock pawl and a drive pawl connected with the apparatus housing and with the lever, respectively. The lock pawl is released by a release lever when the pedal is pivoted toward the released position, and the drive pawl is disengaged when the lever is adjacent the disengaged position, thereby to activate the cable tensioning device.
