Air Break Practice Test

Results

#1. An improper angle between the slack adjuster and brake chamber pushrod when the brakes are applied can be corrected by

Relining the brake.

Pumping the brakes.

Changing the length of the pushrod.

Adjusting the brake.

The slack adjuster can be adjusted to be at about a 90-degree angle to the pushrod. However, a 90-degree angle is NOT a reliable indication that the brake is properly adjusted; the angle can be as much as 10 degrees greater or less, depending on the model of brake adjuster. Adjust the slack adjuster so that pushrod travel is correct for the type of brake chamber.
