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.

• Centralized clutch location and reliable O-ring seals offer improved protection from moisture and road salt
• Easily accessible hex nut simplifies adjustment
• High alloy steel gears, rolled worm shaft and heat treated housing extends life and minimizes internal wear.
• Self-setting control arm can be positioned from -16 to +130 degrees. Reduces the potential for installation errors.
• Severe Service Casting
• The clearance-sensing design maintains a constant and uniform distance between the brake drum and lining
• The gradual adjustment of the S-ABA lowers the risk of over-adjustment during prolonged braking
