(888) 312-8812 Login SignupOn drum brakes that use a 10-spline, 1.5-inch camshaft, the Gunite Automatic Slack Adjuster keeps shoe-to-drum clearance in check as the linings wear. It adjusts itself during normal brake applications, so push rod stroke stays within range between services. The Gunite AS1133 keeps the original arm geometry, so the chamber push rod meets it at the correct angle. Brakes that stay in adjustment stop straighter and help the truck pass roadside inspections.
