Course Description

Covers diagnosis and repair of suspension, steering and brake systems in a laboratory/shop setting. Includes how to perform complete suspension, steering, and brake system inspections and determine what repairs are needed and how to order parts and complete repairs under close instructor supervision. Vehicles serviced are drawn from a pool of customer or school-owned vehicles. This is the capstone course building on the skills, knowledge and abilities learned through successful completion of AM 151 and AM 141. Audit available.

Addendum to Course Description

Students will practice the skills, knowledge and abilities necessary to perform, with supervision, base brake and anti-lock brake (ABS), suspension and steering repairs on import and domestic cars and light trucks. This course prepares students to service these systems with limited supervision, which is the skill level necessary for employment at an apprentice level.

The broader purpose of this course is to provide students with authentic experience in basic industry skills and concepts, to ensure their success in later courses and on-the-job. These skills include tool use, fastener tightening, precision measuring and shop safety. Concepts and abilities that they will put into practice include craftsmanship, professionalism, communication of inspection results and responsible customer service.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Perform comprehensive suspension, steering and brake system inspection, maintenance, diagnosis and repairs with limited supervision.
  • Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.
  • Access and utilize repair information in a rapidly changing technology.
  • 欧洲杯决赛竞猜app_欧洲杯足球网-投注|官网 and implement strategies and processes to solve suspension, steering and brake system repair problems.
  • Perform suspension, steering and brake system repair to professional and ethical standards.
