This course combines lecture and laboratory hands-on activities, focusing on the fundamental operation and servicing of medium and heavy duty vehicle braking systems. Essential topics include a discussion of drum brakes, disc brakes, brake components, system operation, hydraulic and air braking systems. Medium and heavy duty vehicle anti-lock braking systems and traction/stability control systems will be taught utilizing training system simulators. Training simulators will also be used to aid the student in understanding the diagnostic procedures needed to properly service tractor and trailer air brake systems. The laboratory component of the course includes various activities that follow the guidelines of the National Technicians Education Foundation (NATEF). A library/internet research written project concerning some aspect of a medium and heavy duty vehicle’s braking system will be assigned and is an integral component of this course.
