ABSTRACT:
In a somewhat standard system for releasing a parking brake of a wheeled motor vehicle of the type including a mechanical locking panel which coacts with a toothed sector for holding the parking brakes in the set condition, there is provided an improvement for automatically releasing the pawl from the sector when the transmission control mechanism of the vehicle is shifted from park or neutral into a driving condition. The improved device includes an elongated flexible element, such as a cable, extending from the brake releasing mechanism to the transmission control mechanism and a bell crank at the transmission control mechanism which coacts with a movable cam sector to effect the automatic release by pulling the flexible element.
