135.S1031
The Automann 135.S1031 is an automatic slack adjuster for heavy-duty air brake systems. It automatically maintains correct clearance between brake shoes and drum, ensuring consistent braking and even wear. This Haldex-type adjuster replaces a worn or failed manual or automatic slack adjuster, and fits S-cam shafts with a 1-1/2-inch diameter, 10-spline shaft. The arm length is adjustable from 5.5 to 6.5 inches, making it a common replacement on many trucks and trailers.
Universal fit for vehicles using S-cam shafts with 1-1/2 inch diameter, 10-spline, and arm length between 5.5 and 6.5 inches. Always confirm your vehicle's required arm length and spline before installation.
