Auto-Check

Our patented Auto-Check option is designed to provide a method of checking the air chamber stroke without going under the truck.

  • Installed on the ABA facing the center of the vehicle to easily see if brake stroke is in an acceptable range.
  • Bright yellow pointer easily indicates set-up position, indicates working stroke and shows if brake stroke is past acceptable limit without crawling under the vehicle.
  • Offers an extra quality-control check.

The Crewson Adjustment System operates like the windshield wipers on a car — it is utilized only when needed, not continuously.
