Manual Brake Adjuster

A manual slack adjuster (also called a brake adjuster) is a mechanical component in the air brake linkage. This component is used to remove the slack created by wear on the friction element of the brake shoes that normally occurs during operation of the vehicle. This is done manually with the aid of a wrench while the vehicle is being serviced.

According to Federal Motor Vehicle Safety Standard No. 121, if a vehicle is equipped with an air brake system was manufactured after October 20, 1994 it must be equipped with an automatic slack adjuster. Vehicles manufactured before this date may use a manual slack adjuster.
