Investors Relations & Haldex information

Brake adjusters

The Haldex range – from the new generation of S-ABA self-setting automatic brake adjusters to the well-established AA1 automatic brake adjuster – sets the highest standards for performance, reliability and safety.

Key benefits

  • Automatic adjustment of the brake to compensate for lining wear.
  • Adjusting the brake lining to a constant clearance towards the drum to ensure optimized braking performance.
  • Variants for different vehicle and axle types to meet brake performance, regulations and installation requirements.
  • Working principle applicable on all markets having drum brakes.

What sets us apart:

  • Global market leader with over 75 Million Brake adjuster sold since the introduction in the late 60´s.
  • Local production on all major markets simplifies logistics.
  • Improved durability and reliability, which provides a longer service life.
  • Adjusts during brake release when forces on the adjuster are at their lowest which prolongs life.
  • Reduces Maintenance Costs and Extends Service Intervals
  • Clearance-sensing design prevents excessive brake wear and failed roadside inspection, which reduces operating and downtime costs.

Cost-cutting by choosing cheap, inferior copies is a short cut to problems. The impact of poor-quality imitations is not only felt on the road – it adversely affects your profitability. Frequent failure of components, higher turnover of spare parts and shorter service intervals lead to increased running costs and maintenance bills. Buying Haldex original brake parts is an investment in quality that assures safety and cost-effective performance.
