As the very first clearance-sensing brake adjuster, the Haldex AA1 offers customers a higher level of technical efficiency, safety and reliability. 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. Through its innovative self-setting flexible design, the Haldex S-ABA Automatic Brake Adjuster offers two benefits which revolutionize brake adjuster fitting: a free selection of control arm position and error-free installation. The Haldex S-ABA functions correctly whatever the position of the control arm. Previously a brake adjuster could only function properly with the control arm in one predesignated position. Self-setting means no more time-consuming adjustments during installation to fix the control arm to achieve the correct predetermined running clearance.
