Abstract
A brake actuator assembly for an air disk brake includes an actuator housing having a pushrod that is extensible from the actuator housing. A lever arm is disposed inside a caliper housing. The lever arm is actuated by the pushrod for transferring motion from the actuator to a brake pad. A sensor element is disposed between the actuator housing and the caliper housing with the sensor element being sealably engaged to the actuator housing providing an air tight enclosure between the caliper housing and the actuator. An inspection port is disposed in the sensor element providing access to receive a visual sensor and a pressure sensor for identifying a condition of the brake actuator and for identifying a condition of the air tight enclosure.
