Automatic slack adjuster (ASA) for on-highway, linehaul and vocational applications delivers shorter stopping distances and offers longer lining life. Built to be robust and reliable, the industry's lightest-weight automatic slack adjuster optimizes brake performance by increasing payload capacity and enhancing camshaft bracket life. It is the industry's only ASA that adjusts on chamber stroke and reduces maintenance costs by eliminating the need for frequent under-the-truck brake adjustments.
