Abstract
A foot operated actuator is provided for actuating a cable operated vehicle parking brake. The actuator comprises an input lever pivotally mounted on a support for movement to a plurality of brake applied positions where it is held by a pawl-and-sector latch. The lever is standardized and is adapted to receive a plurality of different interchangeable sectors. The sectors have outer peripheral cable-receiving grooves which can have a variety of outer profiles which determine the constant or variable output/input ratio of output cable travel per unit of input lever travel. The lever has a hub having an arcuate surface which receives a mating arcuate surface on the sectors. The sectors each have a radially inwardly depending lobed tab that is axially received in an axially open mating slot on the hub to lock the sectors to the hub.
