Last Updated : April 01, 2024 | Report ID: FBI105088 | Status : Ongoing



Automotive slack adjuster is a significant part of the foundation brake of the vehicle that helps maintain a proper distance between the brake shoes and the surface of the brake drums. It acts as a lever that connects the camshaft and the actuator. This device is usually used in commercial vehicles having air brakes with camshaft. They transmit the braking torque to the camshaft and adjust the gap created between the brake lining and the brake drum which is generated by the wearing of the brake linings. The slack adjuster can be adjusted either manually or automatically. Both the slack adjusters perform the same function unlike the automatic slack adjuster automatically adjusts for brake lining wear and the manual slack adjuster requires a periodic manual adjustment. These adjusters are gaining high traction and are becoming a set standard for the automotive industry as they provide high reliability and consistent operation. This lowers the downtime and operating costs thus increasing the profit ratio.
