Air Brake Refresher

This air brake refresher course helps experienced drivers strengthen their understanding of how air brake systems work and how to operate them safely. The training reviews key components, braking principles, tractor-trailer interactions, common system failures, and safe driving practices.

Air Brake Refresher

Course Overview

Air brake systems play a vital role in commercial vehicle safety, and drivers are expected to maintain a solid understanding of how these systems operate. This air brake refresher training course reinforces essential concepts, helping experienced drivers strengthen their knowledge of system components, braking principles, and safe operating procedures.

The training begins with a review of braking fundamentals, including how vehicle speed, weight, and brake lag influence stopping distance. Learners explore the differences between hydraulic and air brakes, the purpose of compressed air, and how key components, such as supply circuits, service circuits, and spring park brakes, work together to ensure reliable braking. Clear, practical explanations make the material accessible for both daily drivers and those returning to air brake-equipped vehicles.

From there, participants examine tractor-trailer braking interactions, common system failures, brake adjustment practices, and safe braking strategies. The course concludes with driving tips and key inspection techniques to help drivers stay compliant and keep vehicles operating safely in all conditions.
