Haldex Automatic Brake Adjusters deliver unmatched performance over years of service and hundreds of thousands of miles – all the while requiring only minimal maintenance.
By constantly maintaining optimum brake lining-to-drum clearance, Haldex ABAs reduce stopping distances and increase driver control and confidence under all conditions. Optimum brake adjustment helps prevent uneven tire and brake wear; reducing operating expenses and downtime costs.
It’s the most cost-effective ABA you can specify, and it’s backed by the industry’s best ABA warranty.
Unique Design
Improves durability and reliability, which provides a longer service life.
- Reliable ring seal prevents contamination from moisture, dirt and road salt
- Adjusts during brake release when forces on the adjuster are at their lowest which prolongs life
- Heat-treated housing extends life and minimizes internal wear
- Heat-treated internal gears made of high-strength, high alloy steel withstand wear
- Rolled wormshaft increases fatigue strength
Simplifies Installation
- A built-in visual indicator verifies proper installation at a glance, eliminating the templates needed to check other ABA installations
Reduces Maintenance Costs and Extends Service Intervals
- Unique, fully-sealed control arm eliminates the exposed linkage and rubber boots of linkage style adjusters, improving durability and reliability
- Clearance-sensing design prevents excessive brake wear and failed roadside inspection, which reduces operating and downtime costs
The Versatile Haldex Design Fits More Applications than any other Adjuster with its Two ABA Models
