The Haldex Automatic Brake Adjuster (S-ABA) Kit, part number 40020252, is a complete automatic slack adjuster kit for truck and trailer S-cam drum brake systems. The kit features a 6-inch arm length with zero offset, a 1-1/2-inch, 10-spline input bore, and a 5/8-inch arm hole diameter. Body angle is 0°, and the straight grease fitting is positioned at 242°. The included bracket kit (42710585) uses a strap-style anchor bracket. Internal construction uses high-alloy steel gears, a rolled wormshaft, and a heat-treated housing with centralized clutch. The clearance-sensing design maintains a consistent gap between the brake drum and lining, and the gradual adjustment of the S-ABA reduces the risk of over-adjustment during prolonged braking. Call us to confirm proper fit for your application.
