Truck brake adjusters are critical components of the braking system, used to automatically or manually adjust the clearance between the brake pad and the brake drum to ensure stable braking performance. Their core function is to compensate for brake pad wear, prevent brake fatigue, and enhance driving safety. These components require high strength, wear resistance, and corrosion resistance, and are widely used in commercial vehicles such as heavy trucks and trailers. Regular inspection and maintenance can extend their service life and ensure reliable operation of the braking system.
