Product Details

Product description:

A manual slack adjuster is a device used in air brake systems on vehicles, such as trucks and buses, to adjust the clearance between the brake shoes and the brake drums. This adjustment is necessary to ensure proper braking performance and to prevent excessive wear on the brake components.

To adjust a manual slack adjuster:

Park the vehicle on a level surface and chock the wheels to prevent it from rolling.
Locate the manual slack adjuster on the brake assembly. It is usually found near the brake chamber.
Use a proper tool, such as a slack adjuster wrench, to turn the adjusting nut in the appropriate direction to either increase or decrease the slack. Refer to the vehicle manufacturer's specifications for the correct direction.
