Course Description

Brake diagnosis and repair of base brakes and anti-lock systems in a laboratory/shop setting. Covers how to do complete brake inspections and determine what repairs are needed. Ordering parts and completing repairs under close instructor supervision. Audit available.

Addendum to Course Description

Students will practice the skills", knowledge and attitudes necessary to perform, with supervision, base (non anti-lock) brake and anti-lock brake (ABS) repairs on import and domestic cars and light trucks. This course prepares students to service brake 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, at the beginning of their first year in the automotive program, 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 
and shop safety. Concepts and attitudes that they will put into practice include craftsmanship," professionalism and responsible customer service. 

Intended Outcomes for the course

Students who successfully complete AM 115 will be able to:

  • Perform base brake maintenance and repair with limited supervision.
  • Use a Systematic approach to determine causes and corrections of ABS brake complaints.
  • Perform brake repairs with respect for customers and co-workers welfare and property.

Documentation of student performance in the Brake course work may be used in a student's Certificate or AAS portfolio as evidence toward the 
achievement of the following PCC Automotive Service Technology Program Outcomes:

A graduate of the PCC automotive Service Technology Program will be able to:

  • Repair cars and light trucks with limited supervision
  • Formulate strategies and processes to solve vehicle repair problems
  • Perform vehicle repairs to the highest professional and ethical standards
