Haldex 40020236 S-ABA Clearance Sensing Automatic Slack Adjuster

The Haldex 40020236 is a premium S-ABA (Self-Setting Automatic Brake Adjuster) designed for heavy-duty commercial vehicles and trailers. This clearance-sensing slack adjuster automatically maintains optimal brake shoe-to-drum clearance, ensuring consistent and reliable braking performance throughout the service life of your brake components.

Key Features:

• Clearance-sensing technology keeps brakes unaffected by deflection or thermal expansion
• Self-setting design makes installation quick and easy without pre-adjustment
• Functions correctly regardless of control arm position for flexible application coverage
• Gradual adjustment reduces risk of over-adjustment during prolonged braking
• Constructed with high-quality ductile iron housing and heavy-duty steel alloy worm gear
• Exceeds SAE J1462 specifications for automatic slack adjusters
• Backed by Haldex 6-year, 1 million mile warranty

As a lever connecting the brake chamber to the camshaft, this automatic slack adjuster compensates for normal brake wear while maintaining proper actuator stroke. The S-ABA design provides consistent and precise adjustments for optimum lining-to-drum clearance, making it one of the most reliable tools for monitoring brake performance and maximizing brake life in commercial vehicle applications.
