Overview
A slack adjuster that has quit adjusting is what turns a healthy set of foundation brakes into a long-stroke brake job. This Meritor-Type Automatic Slack Adjuster distributed by FleetPro Parts & Tires mounts on S-cam foundation brakes and keeps brake stroke in adjustment automatically, so shoe clearance stays where the brakes were set instead of drifting out between services. It ships as an automatic brake slack adjuster with hardware included - the 179.YK5005 Clevis Kit is in the box with the unit. Manufactured by Automann to Fleet Standard specifications, it is stocked heavily right here in our Hanover Park, Illinois warehouse for lightning-fast shipping to fleets, diesel repair shops, and owner-operators nationwide.
Stroke In Adjustment: The Meritor-Type Slack Adjuster Advantage
This is the Automatic, Type B, Meritor Type design, splined 1-1/2in-10 and swinging a 5-1/2in arm to a 5/8in-18 clevis. Those three numbers are what decide whether an adjuster belongs on the axle in front of you: the spline has to index on the camshaft, the arm length has to match the leverage the axle was engineered around, and the clevis thread has to match the chamber pushrod. Miss one of them and the brake either will not assemble or will never make its rated stroke.
Because the take-up is automatic, the adjusting that used to be a line item at every PM happens on its own as the linings wear. Stroke stays short, and both wheel ends on the axle keep applying together instead of one side quietly doing more of the stopping. The included 179.YK5005 Clevis Kit matters more than it looks on the box: a clevis that has been worn oval by a season of stroke puts slop right at the pushrod connection, and slop there shows up as stroke that no adjuster can recover.
At FleetPro Parts & Tires, we know a brake job is only right when the adjuster is right. This Automann unit is a direct replacement for highly searched industry numbers including Meritor R802317, Meritor R803025, Meritor A273275A1145, Euclid E11410 and E11410A, and Autocar 3947623. Order it by Automann distributor number 139.1033.
