Course DescriptionIntroduces principles of automotive braking systems. Practice disassembly/assembly of brake system components using school owned equipment including proper measuring and machining of brake drums and discs. Audit available.
Addendum to Course Description
This course is designed for students with no previous industry experience. Students will develop 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 will prepare students for Brakes II (AM115), where they will practice learned skills on customer vehicles until they can diagnosis and repair brake systems with limited supervision. This 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 ASE style test taking. Concepts and attitudes that they will put into practice include safety, craftsmanship, professionalism and responsible customer service.,
Intended Outcomes for the course
? Perform a complete vehicle brake inspection, including measurement and evaluation of the base brake friction, hydraulic, wheel bearing, parking brake and power assist components.
,Perform brake drum and rotor refinishing.
,Demonstrate professional, safe and ethical practice in the performance of brake repair.
Outcome Assessment Strategies
To reach these goals, students will demonstrate the course outcomes for Brakes I by completing the following tasks:,
1. Perform a complete brake inspection and service.,
This is the capstone performance for Brakes I, done near the end of the course. Preparation for this performance will be the completion of the
,following sub-tasks in labs throughout the course:
Overhauling drum and disc brake systems
,Servicing brake hydraulic components
,Servicing conventional wheel bearings
,Performing repairs to correct brake vibration
,Performing power assist brake diagnosis
,Adjusting parking brake systems
,Identify an ABS system by its major characteristics and perform
,ABS service and diagnostic tests
2. Demonstrate professional skills and attitudes throughout AM 105 by:,
Maintaining good attendance
,Using safe shop procedures
,Demonstrating respect for other students and school property
,Participating in and completing all required activities
3. Demonstrate preparedness for ASE testing by achieving passing scores on all written exams,
Critical to the effective diagnosis and repair of any automotive system is an understanding of how and why certain components work. On today's automobile, this is often more useful for the technician than the ability to perform a particular adjustment or replacement. A technician must also have the ability to determine which repairs are in the customer's best interest, and understand how safe service procedures are in their own best interest. To develop this background understanding of automotive brake systems, students in AM 105 will explore the following concepts:,
Health and safety,
Hazards of brake dust, importance of shop cleanliness
,Hazards of chemicals used in brake systems and repair
Professional business and personal conduct,
,Communicating with customers
,Customer satisfaction as business strategy
,Cooperative problem solving
,Work absence and attendance
,Heat and Friction
,Hydraulic theory - Pascals law
Specific system and component operation,
Hydraulic - caliper, wheel cylinder, master cylinder, quick-take-up
,Master cylinder, control valves, ABS, brake fluids, brake lines
,Disc brakes - floating, fixed, low drag, phenolic, parking brake calipers
,Drum brakes - servo, non servo, self-adjusting
,Power assist - vacuum, Powermaster, Hydroboost
,ABS brake operation - modes of operation, sensors, OBD, limitations
Skills developed in AM 105,
In Brakes I, students will build an inventory of the following repair skills to prepare for a career as a brake technician. Further skills will be developed and all skills will be practiced in AM 115.,
Evaluate and overhaul wheel cylinders
,Evaluate and overhaul Master cylinders
,Evaluate and overhaul calipers
,Measure and adjust master cylinder push rods
,Bench bleed master cylinders
,Adjust brake switches
,Inspect flexible brake lines for wear
,Flare and bend steel brake line
,Bleed brakes using gravity, manual, pressure, and vacuum methods
,Bleed an ABS system / front and rear hydraulic circuits
,Diagnose control valve malfunctions
,Properly select, handle, and install brake fluid and dispose used fluid
Measure and evaluate lining thickness

,Research applicable vehicle service information
,Use vehicle identification numbers
Evaluate a Wheel Speed Sensor for open circuit, air gap, tone ring and EMI failures
,Depressurize a high pressure ABS type system
,Bleed an ABS system (all circuits) using the recommended scanner
,Determine number of wheel speed sensors, hydraulic channels, and
,type of OBD on a given ABS system; describe OBD parameters
,Perform manual ABS code retrieval and erase code
,Perform ABS code retrieval and erase code using a scanner
,Perform Scanner live data and auto-test
Note: The process skills necessary to diagnose and repair ABS systems are developed in Brakes II. Assessment of these skills is done in Brakes II.,
1. Perform a complete vehicle brake inspection", including measurement and evaluation of the base brake friction, hydraulic, wheel bearing, parking brake and power assist components.
,2. Perform brake drum and rotor refinishing.
Students measure brake rotors and drums compare vehicle test results to manufactures specifications.
,Students measure brake pad and shoe linings compare vehicle test results to manufactures specifications.
1. Perform a complete vehicle brake inspection, including measurement and evaluation of the base brake friction, hydraulic, wheel bearing, parking brake and power assist components.
Students work teams communicate with staff to check out tools, school cars, and have repair orders written for lab projects.
,Students present a verbal report to the class on a subject of their choice related to current industry technical advances, innovations, safety standards, and/or diagnostic or trouble shooting procedures related to steering and/or suspension.
