Gunite Air Brake Automatic Slack Adjuster

Eliminate the risk of out-of-service violations and ensure consistent stopping power with the Gunite Air Brake Automatic Slack Adjuster. Designed for heavy-duty drive axle applications, this component utilizes a clearance-sensing mechanism that adjusts the brake shoe position during the application stroke rather than the return. This specific operation allows the Gunite AS1141 to distinguish between normal drum expansion and actual lining wear, preventing the dangerous over-adjustment that leads to dragging brakes and overheated wheel ends. To ensure long-term reliability, the internal worm wheel is drilled to allow fresh grease to penetrate deep into the spline interface, preventing the seizing issues common in harsh operating conditions. By maintaining precise stroke length automatically, it reduces the need for frequent manual corrections and keeps your fleet compliant with safety regulations.
