Automatic adjusters should _________.

Automatic adjusters should not have to be adjusted manually except when you are performing maintenance on the brakes and during installation of the slack adjusters.

Automatic adjusters, also known as self-adjusting brake adjusters or slack adjusters, are designed to automatically maintain the proper brake shoe-to-drum clearance as the brake linings wear down over time. These adjusters utilize mechanisms that automatically compensate for brake lining wear, ensuring consistent braking performance without the need for frequent manual adjustments.

In normal operation, automatic adjusters continuously monitor the brake shoe clearance and adjust it as necessary to maintain optimal brake performance. This self-adjusting feature reduces the need for manual adjustments and helps ensure that the brakes maintain their proper functioning throughout the lifespan of the brake linings.

However, there are certain situations where manual adjustment of the automatic adjusters may be required. This includes maintenance procedures such as inspecting, lubricating, or replacing brake components, as well as during the installation of slack adjusters. These manual adjustments are necessary to ensure proper installation and functionality of the brake system.
