This is a slack adjuster, a critical component in the braking system of heavy-duty trucks that automatically maintains the correct air gap between the brake lining and the drum. It is manufactured to meet stringent Volvo specifications for durability and precise adjustment, ensuring consistent braking performance unlike a worn or improperly adjusted unit. A malfunctioning slack adjuster can lead to reduced braking effectiveness, excessive brake pedal travel, or premature wear of brake components.

Failure Symptoms

A common symptom of a failing slack adjuster is an increased amount of travel in the brake pedal or treadle valve before the brakes engage. The brakes may also feel inconsistent, with some applications feeling weaker than others. If left unaddressed, this can lead to significantly reduced braking efficiency, increasing stopping distances and posing a safety risk.

Installation Tip

Ensure the brake chamber pushrod is in the correct position before installing the new slack adjuster to allow for proper initial adjustment. Avoid over-stroking the brake chamber during installation, as this can damage the new adjuster.

Service Note

When replacing a slack adjuster, it is essential to inspect the brake linings, drums, S-camshaft, and air chamber for wear or damage.
