How To Back Off Automatic Slack Adjusters

One important part of this maintenance is taking care of the automatic slack adjusters. They play a vital role in your truck’s braking system, making sure your brakes are in excellent condition. This blog post will guide you on how to back off automatic slack adjusters.

Understanding Automatic Slack Adjusters

Automatic slack adjusters, often referred to as ASAs, are designed to keep the proper stroke or adjustment of the brake actuator push rod.

If the distance becomes too great, it can affect the brake’s response time and overall performance.
