Overview
Put the bite back in a trailer's foundation brakes with this Brake S-Camshaft distributed by FleetPro Parts & Tires. Manufactured by Automann for Fruehauf Pro-Par axles with 16-1/2in brakes, this left-hand cam turns slack adjuster motion into brake shoe spread at the wheel end. A cam with a worn head profile or rounded splines gives up brake torque long before the linings are gone, and it is exactly what an inspector finds sitting behind a long pushrod stroke. 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.
Trailer Braking Restored: The Fruehauf Pro-Par S-Camshaft Advantage
This left-hand (LH) camshaft runs 16.125in long with a 1.375in head and 37 splines on a 1.625in diameter โ the exact combination the Fruehauf Pro-Par axle expects behind a 16-1/2in brake. Get any one of those three wrong and the slack adjuster either will not seat on the spline or runs out of usable travel, so match length, head and spline count before you order.
Camshafts are sold per side, so this covers the LH position only; order the right-hand cam for the opposite end of the axle. Rebuild the cam tube while the drum is off โ repair kits 110.2101 and 110.2102 carry the bushings and hardware, and a fresh cam dropped into worn bushings simply repeats the failure you just paid to fix.
At FleetPro Parts & Tires, we know that on a trailer the brakes are the entire safety story. This Automann camshaft is a direct replacement for highly searched industry numbers including Meritor 2210R2488, Euclid E1563, Haldex CS41528, Fruehauf AXA000420001 and Spicer 17-621.

Key features
- Exact Pro-Par Geometry: 16.125in length, 1.375in head and 37 splines on 1.625in match the Fruehauf Pro-Par axle behind 16-1/2in brakes.
- Restores Trailer Brake Torque: A fresh head profile spreads the shoes fully again, recovering the stopping power a worn cam quietly gives away.
- Cures Long Pushrod Stroke: Undamaged splines let the slack adjuster seat and hold, so the stroke stops creeping out between adjustments.
- Rebuild-Ready: Pairs with repair kits 110.2101 and 110.2102 so the bushings and hardware go in with the new cam, not after it.
- True Left-Hand Part: Sold per side as a genuine LH camshaft, so the hand is right the first time instead of forced into place.
