Manufacturer
Product Description
Air Brake Automatic Slack Adjuster
Features & Benefits
- Delivers balanced braking force across compatible axle applications
- Adjusts brake lining clearance automatically for consistent brake response
- Reduces manual under-chassis brake adjustment during routine maintenance
- Uses stroke-sensing technology to support proper drum brake adjustment
Meritor Automatic Slack Adjuster
The Meritor Automatic Slack Adjuster helps maintain brake adjustment on heavy-duty air brake systems as the linings wear. Its 1.50-inch, 28-spline bore and 6-inch arm length give the part clear fit details for matching compatible brake setups. The Meritor R802491 uses a stroke-sensing design with a green piston layout for automatic brake clearance control during normal operation. With the correct slack adjuster installed, the brake system can maintain more consistent stroke and response across routine service intervals.
