When the brake pedal is pressed, the S-shaped head of this camshaft rotates to spread the brake shoes apart against the drum, creating the stopping force. It is specifically made for Meritor Q Plus style 16.5-inch diameter brakes and is typically replaced when the splines wear out, the head gets flat-spotted, or the bushings and journals become excessively worn, leading to poor brake performance.
