Product description:

A manual slack adjuster for trailer 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:

1.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.

2.Turn the adjusting nut slowly and check the clearance between the brake shoes and the drum as you go. You may need to apply the brakes and release them a few times to make the adjustment.

3.Once the correct clearance is achieved, tighten the locknut to secure the adjustment in place.

It is important to regularly inspect and adjust the slack adjusters as part of routine maintenance to ensure the safety and reliability of the braking system. If you are not familiar with vehicle maintenance or brake systems, it is recommended to have a qualified mechanic perform this task.
