Overview
Keep brake stroke in adjustment without reaching for a wrench with this Automatic Slack Adjuster distributed by FleetPro Parts & Tires. Built by Automann for Haldex-type drive axle applications, it converts brake chamber pushrod stroke into S-cam rotation and takes up shoe clearance on its own as the linings wear. A worn or seized slack adjuster is how a truck ends up with a long pushrod stroke and out-of-adjustment brakes, one of the surest ways to fail a roadside inspection. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.
Stroke Under Control: The Haldex Type Slack Adjuster Advantage
This unit uses the Haldex type 1-1/2 in.-10 spline with a 5.5-6.5 in. arm, the combination found across Eaton and Meritor drive axle applications. Mounting hardware is included, so it goes on complete instead of sending you back to the counter for a bracket halfway through the job. Because it self-adjusts, it holds S-cam foundation brakes at the right shoe clearance through the life of the lining rather than drifting long between manual adjustments and quietly costing you brake torque.
Slack adjusters work as a set. Replace them in axle pairs so both wheel ends stroke the same distance at the same pressure โ a mismatched pair brakes unevenly no matter how good the new unit is, and it chews the lining on whichever side is doing the extra work. Automann builds this one to Premium specification, which is where you want to be on a component that spends its life exposed to road salt and vibration under the chassis.
At FleetPro Parts & Tires, we know compliance is what keeps the truck earning. This Automann slack adjuster is a direct replacement for highly searched industry numbers including Haldex 40010121, Meritor R806022, Euclid E6924B, Eaton 818552 and Peterbilt 0305886.
