Abstract
A vehicle parking brake control has an extendable pin with three faces, and a roller on a lower surface. The faces correspond to engage, hold, and disengage of a parking brake. The control also has a lever rotatably connected to it, where the lever has a roller at a lower lever surface. The roller being capable of rotational contact with the pin faces. Further, the control has a base with an upper surface for the pin roller to move across. When the parking brake is engaged the lever roller is in contact with a first face, when the brake is on hold the lever roller is in contact with a second face, and when the brake is in the disengage position the lever roller is in contact with a third face of the extendable pin. Consequently, the rollers provide a reliable lifelong operation of the control over prior controls.
