Abstract: A brake pedal contacts a pin holding the push rod for the master cylinder, applying the hydraulic service brakes in the normal manner when the pedal is depressed. When the transmission lever is shifted into the park position a solenoid type servo is energized, engaging a pawl, mounted on the brake pedal, with a gear sector pivoted about the pivot point of the brake pedal. A one-way spring clutch is energized to hold the link in which the push rod pin is installed in the applied position during parking brake apply, retaining hydraulic brake pressure during that operation. When shifting to park, the brake pedal is raised by a vacuum servo so that the pedal can be actuated to apply the parking brake without contacting the push rod pin, and therefore without hydraulic pressure resistance. Movement of the pedal with the pawl engaged exerts tension on the parking brake cable through the gear sector to apply to parking the brake.
