Midland Haldex 40911095 is an Automatic Brake Adjuster (ABA) for truck and trailer air brakes, supplied without hardware. It turns pushrod movement into rotation at the camshaft, and as the lining and drum wear it takes up the slack in small steps so shoe-to-drum clearance and stroke stay consistent without hand adjusting.
Excessive pushrod stroke is the classic sign that an adjuster is tired, and a unit that binds or does not return fully to the released position needs attention too. Drivers often get no dash warning, so the wheel-end check matters. A genuine Midland Haldex part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
A factory handling fee of $25.00 per order is added at checkout.
