139.2837
The Automann 139.2837 is an automatic slack adjuster designed as a direct replacement for Meritor-type air brake systems on heavy-duty trucks and trailers.
It automatically adjusts brake clearance as the brake linings wear, maintaining consistent braking performance and reducing the need for manual adjustments. This unit features a 6-inch arm length with a fine spline connection, and is commonly replaced when a slack adjuster is worn, damaged, or fails to maintain proper stroke. Always verify the correct arm length, spline type, and mounting orientation for your specific axle and brake chamber configuration.
