Description

Overview

The Manual Slack Adjuster 10 Spline 38mm Cam Brake converts air chamber pushrod travel into S-cam rotation, so your drum brakes apply with the correct leverage. This manual adjuster suits common 1 1/2″ (38mm) 10-spline camshafts used on heavy vehicle foundation brakes. It is a practical replacement when you want consistent brake feel after lining wear or service work.

Compliance and Safety

Brake performance depends on correct installation and adjustment, so confirm chamber stroke and camshaft condition before you set final clearance. Inspect clevis pins, yokes, and bushes for wear because looseness can mimic an out-of-adjustment brake. Re-check adjustment after initial bedding-in and include it in your regular service schedule.

Trailer Applications

Manual Slack Adjuster 10 Spline 38mm Cam Brake suits S-cam foundation brake setups found on many heavy trailers and prime movers. It can suit drum-braked semi-trailers, dog trailers, and general purpose combinations that run 38mm 10-spline camshafts. If your axle uses a different spline count, arm style, or offset, choose the matching variant instead.
