Which of the following is true of an automatic slack adjuster?
A) signals driver when brakes need adjusting
B) automatically defines the amount of brake force required
C) automatically sets the amount of hold-off chamber force
D) adjusts brake free stroke as friction surfaces wear
Automatic Slack Adjuster
A device in air brake systems that automatically adjusts the brakes as needed to maintain proper clearance between the brake shoes and drums.
Brake Free Stroke
The amount of movement or travel the brake pedal or lever undergoes before the brake mechanism starts to engage.
Friction Surfaces
Areas where two materials come into contact and movement between them is resisted by friction, important in braking systems and clutches.
- Apprehend the functions and roles of components in air brake systems, for instance, air compressors, slack adjusters, and brake chambers.
- Distinguish between the types and functions of different slack adjusters and their adjustment mechanisms.

Final Answer :
D
Explanation :
Automatic slack adjusters are designed to maintain the correct distance between the brake shoes and the drum as the friction materials wear down, ensuring the brakes are properly adjusted at all times.
