Stemco Automatic Brake Adjuster
The Stemco Automatic Brake Adjuster maintains proper slack adjustment by continuously tracking brake-stroke movement and resetting clearance within its mechanical limits. Its 5-inch and 6-inch arm compatibility offers installation versatility across multiple axle configurations, while the 1.5-inch, 28-spline interface connects firmly to the camshaft for steady rotational control. This adjuster eliminates the problems associated with periodic manual setups, allowing brake systems to keep consistent shoe-to-drum spacing through repeated braking cycles. The absence of an auto-check port streamlines the adjuster’s body design for straightforward fitment. Get the Stemco MK22153S today.
