Overview

Keep your trailer brakes in adjustment with this premium aftermarket Haldex-Type Automatic Slack Adjuster distributed by FleetPro Parts & Tires. It links the brake chamber push rod to the brake camshaft on trailer axles with 16-1/2 in. brakes and adjusts itself as the linings wear. A worn or seized slack adjuster lets push rod stroke grow until the brakes are out of adjustment, which means longer stops and an out-of-service brake violation at inspection. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

Brakes Kept in Adjustment: The Automatic Slack Adjuster Advantage

This Automann automatic slack adjuster (Part # 135.2840) is a Haldex-type unit with a 1-1/2 in.-28 spline and a 5-1/2 in. arm at 0 degree, built to Automann's Fleet Premium level. It comes with the 135.H0563 kit: anchor bracket plate, flat stud and mounting hardware, so the install hardware arrives in the same box. If your fleet runs self-setting adjusters, Automann also makes a self-setting version as 135.S2840.

At FleetPro Parts & Tires, we know a brake job is only right when the part is right. This slack adjuster is a direct replacement for highly searched industry numbers including Haldex 40910471 and 40910683, Meritor R806019 and M807019, and Eaton 808138. Check the spline and arm length on the old unit before you order.
