This is a cam bush for the Isuzu FTR model truck. Camshaft bushings provide support and flexibility in the proper operation of a vehicle’s braking system. A camshaft bushing may become worn, allowing some non-rotational movement of the camshaft. Pulling on the camshaft by hand generates a combination of lateral and rotational movement and does not provide an accurate assessment of the bushing’s wear. However, any wear or looseness in the camshaft bushing will affect the overall brake stroke to some degree.
