GUELPH, Ont. — Haldex has recently announced that its Self-Setting Automatic Brake Adjuster (S-ABA) is available for truck and tractor applications in addition to trailer applications.
The S-ABA has a unique design that revolutionizes correct fit with easy installation, improved performance, extended service life and streamlined inventories, noted company officials.
The self-setting adjuster establishes its own reference point when the control arm sets itself to any angle within the total range of permissible control arm positions allowed with current adjusters. Its clearance-sensing design maintains a constant and uniform distance between the brake drum and lining regardless of the control arm installation angle.
The gradual adjustment of the S-ABA maintains this lining-to-drum clearance, which lowers the risk of over-adjustment during prolonged braking. This optimized brake adjustment helps prevent brake wear, which reduces operating and downtime costs.
Like the standard ABA, the S-ABA incorporates several design advances to maximize the service life, including heat-treated housing, centralized clutch location, heat-treated internal gears made of high-strength, high-alloy steel, and a rolled wormshaft to further increase the fatigue life.
