Features & Benefits
- Twenty-eight spline setup engages the camshaft connection during application

- Six-inch arm length provides leverage through the brake linkage path
Meritor Air Brake Automatic Slack Adjuster
Brake stroke control happens in the linkage, and the Meritor Air Brake Automatic Slack Adjuster manages the connection between chamber pushrod travel and camshaft rotation. Its 6-inch arm, 28-spline count, and unhanded design place it in commercial air brake service where consistent adjustment matters after repeated stops. The adjuster responds as lining wear changes, keeping the foundation brake movement within its intended range. From the linkage position, the Meritor R806016A restores automatic adjustment control without adding clevis hardware.
