Why are automatic slack adjusters used?

To strengthen the brake system
To avoid regular manual re-adjustments
To reduce air pressure usage
To increase vehicle speed

The correct answer is: To avoid regular manual re-adjustments

Slack adjusters are designed to be automatic to avoid the regular and manual hassle of re-adjusting the brakes. This is not done to increase vehicle speed, reduce air pressure usage, or strengthen the brake system. It is simply a more efficient and convenient way to ensure that the brakes are properly adjusted without the need for constant manual adjustments.
