Manual Brake Adjuster

A manual slack adjuster (also called a brake adjuster) is a mechanical component in the air brake linkage.

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.
