B rakes cannot simply be adjusted for 'stroke' variation to maintain a correct running clearance not by a long stroke!

Haldex have become world leaders in automatic brake adjustment by developing the 'clearance' adjustment principle. Over the last 25 years (and 20 million plus units), the 'clearance' principle has been proven time and again by leading brake manufacturers to be the most reliable method of adjustment. Stroke' adjusters react quickly to heat expansion and adjust up for spurious slack caused by various factors. Haldex adjusters take up slack slowly and exponentially. They also have the capacity to compensate for clearance caused by drum contraction, which drastically reduces the risk of brake seizure.
Having spent years and millions of pounds on research and development, and using only the finest quality materials, production processes and component engineering. Haldex have perfected the most cost effective automatic brake adjusters around. We think you will agree once you consider the cost of freeing seized brakes and going through linings and drums faster than you need!
