AUT 503 - Automotive Brake Systems


Last Date of Approval: 4-2021

3 Credits
Total Lecture Hours: 22.5
Total Lab Hours: 45
Total Clinical Hours: 0
Total Work-Based Experience Hours: 0

Course Description:
The course covers the latest procedures of inspecting, measuring, diagnosing, and the repairing of drum and disc brakes. Classroom and lab instruction will be utilized to teach students the latest procedure for inspecting, measuring, diagnosing, and repairing the modern brake systems in use today. This course will help students refine their critical thinking skills as they evaluate various topics and concepts while searching for underlying connections between the concepts, which is a skill that should be beneficial in any/all types of careers. The students will increase their mechanical aptitude that can be used in many aspects of their life.
