Overview
Take the guesswork out of initial brake setup with this Haldex Self-Setting Automatic Slack Adjuster distributed by FleetPro Parts & Tires. Built by Automann for drive axle applications, it converts brake chamber pushrod stroke into S-cam rotation and self-adjusts brake shoe clearance as the linings wear. Worn or seized slack adjusters cause long pushrod stroke and out-of-adjustment brakes, still a top CSA violation and the fastest way to turn a routine inspection into a bad afternoon. 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.
Set Itself and Stay Set: The Haldex Self-Setting Advantage
The self-setting design is the reason to reach for this one. It fits the Haldex Self-Setting Type 1-1/2in-28 x 5-1/2in Arm position, runs a 1/2in clevis hole, and finds its own starting clearance on installation instead of depending on a technician nailing the initial setting by feel. From there it keeps taking up clearance automatically for the life of the lining.
It also can be used in place of the standard version, 135.2835, so one part number covers both the self-setting and standard positions on drive axles. The 135.H0553 Bracket Kit is included, meaning the anchor bracket arrives with the unit rather than as an afterthought. Replace slack adjusters in axle pairs so both wheel ends stroke the same distance at the same pressure.
At FleetPro Parts & Tires, we know compliance is what keeps the truck earning. This Automann unit is a direct replacement for highly searched industry numbers including Haldex 40020231 and 40920019, Volvo MID40020231, Freightliner HDX40020231, Mack 539640020231 and IHC ZZ40020231.
