Stemco Automatic Brake Adjuster

Maintain optimal stopping power without the need for constant manual intervention with the Stemco Automatic Brake Adjuster. This clearance-sensing unit automatically regulates the distance between the brake lining and the drum, ensuring the S-cam remains at the most effective mechanical angle. While this specific model is engineered without the Auto-Check™ visual pointer, it utilizes the same high-strength gearset and patented reduced-wear clutch found in the rest of the Crewson line. The 1.5-inch 28-spline internal profile provides a zero-play connection to the camshaft, while the dual-hole arm (5-inch and 6-inch centers) allows for versatile mounting across various axle and chamber configurations. This Stemco MK22103S adjuster is the ideal choice for fleets that require the safety of an automatic system in a streamlined, low-profile housing.
