It is designed to adjust exactly and gradually when it matters, maintaining a constant clearance between lining and drum, whatever the conditions or driver's braking style. The adjustment mechanism is integrated into a robust, high-quality housing that protects it from knocks, dirt and moisture and assures a long service life even in hostile driving environments. Key benefits: Constantly maintains brake lining -to-drum clearance, reducing stopping distances and increasing driver's confidence under all conditions Heat-treated housing extends life and minimizes internal wear Heat-treated, high strength, high alloy steel internal gears withstand wear Reliable o-ring seals improve protection from moisture, dirt and road salt Verifies proper installation at a glance through its built-in visual indicator, eliminating the cumbersome templates needed to check other ABAs. What sets us apart: Global market leader with over 75 Million Brake adjuster sold since the introduction in the late 60´s Better durability and reliability, which provides a longer service life Reliable ring seal prevents contamination from moisture, dirt and road salt Adjusts during brake release when forces on the adjuster are at their lowest which prolongs life Clearance-sensing design prevents excessive brake wear and failed roadside inspection, which reduces operating and downtime costs Simplifies adjustment during installation and brake lining replacement with an easily accessible adjustment hex - requiring no locking pawls to remove or disengage.
