A quiet apply push to release control pedal system includes a frame to mount the system to a vehicle. The frame also includes a geared rack and a pedal arm and a quiet apply carriage are rotatably mounted to the frame. The quiet apply carriage has a geared quiet apply mechanism which engages the geared rack and a cable carrier to which a control cable can be attached. Pushing the pedal moves the carriage to tension a control cable attached thereto by rotating the quiet apply mechanism along the geared rack. The quiet apply mechanism includes a clutch which prevents the gear from rotating in a direction to release the tension in the cable unless the clutch is released. The carriage also includes a pawl and toggle mechanism which locks the pedal arm to rotate with the carriage to tension the cable when the pedal is first pressed. The pawl and toggle unlocks the pedal from the carriage after the cable has been tensioned so that pressing the pedal then rotates the pedal with respect to the carriage, a release tab on the pedal arm abutting the clutch to release it to allow the tension to be removed from the cable. A retainer spring keeps the release tab in abutment with the release of the clutch until the release engages a release surface on the rack which keeps the clutch released until the pedal and carriage have returned to their initial positions, where the cable is not tensioned, and the pawl re-locks the pedal to the carriage.
