Meritor Automatic Slack Adjuster

The Meritor Automatic Slack Adjuster (also called an automatic brake adjuster or air brake auto slack adjuster) is a key part of the S-cam air brake system on commercial trucks, trailers, and buses. It connects the brake chamber pushrod to the S-cam shaft. It also automatically keeps brake shoe-to-drum clearance in adjustment as the linings wear.

Key Features:

• Self-adjusting design that keeps brake stroke consistent, so you don't have to adjust it by hand as often
• Helps keep brake performance and chamber stroke within the range the system is designed for
• Built for heavy-duty commercial vehicle use
• Works with S-cam air brake setups
• Available in several configurations, each under its own part number

Meritor is a well-known supplier of drivetrain, braking, and axle components for commercial vehicles. Using a quality automatic slack adjuster helps keep brake force balanced between wheel ends. It also helps limit uneven lining wear and supports safe, reliable stopping. Choose the right variant for your application.
