An improved brake system includes a parking brake piston fixed to the backing plate of a brake friction material for a large vehicle. Service brake pistons are positioned about the parking brake piston. Both the service and parking brake may selectively actuate the brake. Upon actuation by the service brake piston, the parking brake piston moves with the backing plate. The parking brake is set by a parking brake actuator which is connected through a connector to the parking brake piston. When the service brake is set, it causes the connector to move with the parking brake piston. If adjustment is necessary, the connector will hit a stop, and adjustment of the connector along the parking brake piston will occur to compensate for wear on the friction material.
