Overview

Get full brake torque back at the wheel end with this Brake S-Camshaft distributed by FleetPro Parts & Tires. Manufactured by Automann for Eaton ES drive axles running 16.5in brakes, this right-hand cam turns slack adjuster motion into brake shoe spread at the wheel end. When the cam head profile flattens or the splines round off, pedal effort climbs, stopping distance grows and the slack adjuster stops holding its setting no matter how many times it is adjusted. 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.

Full Brake Torque Restored: The Eaton ES S-Camshaft Advantage

This is the right-hand (RH) cam, measuring 15.25in long with a 1.125in head and 10 splines on a 1.5in diameter. Those three dimensions are what decide whether a camshaft is the correct one, and here they are matched to the Eaton ES drive axle behind 16.5in brakes. A correct head profile spreads the shoes evenly across the drum, so lining wear stays flat and the slack adjuster can do its job instead of chasing a cam that no longer lifts.

Camshafts are a per-side part, so this one covers the RH position only โ€” order the matching left-hand cam for the other end of the axle. While the wheel end is apart, replace the cam bushings, seals and hardware at the same time. A new camshaft dropped into worn bushings develops the same radial play that ruined the original, and it will do it in a fraction of the miles.

At FleetPro Parts & Tires, we know a brake job is only right when the part number is right. This Automann camshaft is a direct replacement for highly searched industry numbers including Eaton 811407 and Meritor R607284.

Key features
  • Correct Eaton ES Geometry: 15.25in length, 1.125in head and 10-spline 1.5in shaft match what the Eaton ES drive axle expects behind 16.5in brakes.
  • Restores Brake Torque: A fresh head profile spreads the shoes fully again, cutting the pedal effort and stopping distance a worn cam costs you.
  • Even Lining Wear: A cam that lifts both shoes evenly keeps lining wear flat, so the linings last the miles they were sold for.
  • Slack Adjuster Holds Setting: Undamaged splines let the slack adjuster seat square and stay in adjustment instead of drifting long.
  • RH Side Specific: Sold per side as a true right-hand camshaft, so you fit the correct hand rather than forcing a mirrored part.
