The Midland Haldex 40020226 is an S-ABA (automatic brake adjuster) designed for air-braked truck and trailer axles. It features a 5-1/2" arm length with zero offset, a 1-1/2" spline bore on a 10-spline count, and a 0° body angle for a straight-mount configuration. The arm hole diameter is 1/2". The grease fitting is a straight type located at the 242° position. Anchor bracket style is strap; compatible bracket kit is 42710543. The clearance-sensing design maintains a consistent gap between the brake drum and lining, and the gradual adjustment mechanism reduces the risk of over-adjustment during extended braking.
