Haldex Sensing Automatic Brake Slack Adjuster Kit

The Haldex Sensing Automatic Brake Slack Adjuster Kit is an AA1 clearance-sensing automatic brake adjuster (ABA), also called an automatic slack adjuster, for heavy-duty air brake systems. It mounts on the brake camshaft. As the linings wear, it adjusts automatically to keep the lining-to-drum clearance correct, so stopping performance stays consistent.

Key Features:

• Clearance-sensing operation: makes gradual, precise adjustments for optimum lining-to-drum clearance.
• Resists deflection and heat: clearance sensing keeps brake adjustment from being thrown off by component deflection or thermal expansion.
• Durable internals: heat-treated internal components and an O-ring seal help protect against contamination and wear.
• Easy installation and service: an accessible adjustment hex makes setup and lining replacement simpler. A built-in visual indicator confirms correct installation without templates.
• Haldex engineering: Haldex is a well-known name in automatic brake adjusters for commercial vehicles.

Use this kit to replace a worn or failed automatic slack adjuster, such as one that no longer holds proper brake stroke, has excessive free play, or is corroded or damaged. Choose the variant that matches your camshaft and brake setup.
