AUT 121 - Automotive Brake Systems Service Lab


Credits: 3
Lab/Lecture: One lecture. Four lab.

Emphasizes service of automotive and light truck brake systems. Topics will include: power assist units diagnosis and repair, brakes related (Wheel Bearings, Parking Brakes, Electrical, Etc.), and antilock brake and traction control systems.
Course Outcomes:
Students will be able to:
  1. test pedal free travel with and without engine running; check power assist operation;
  2. check vacuum supply (manifold or auxiliary pump) to vacuum-type power booster;
  3. inspect the vacuum-type power booster unit for vacuum leaks; inspect the check valve for proper operation; determine necessary action;
  4. inspect and test hydro-boost system and accumulator for leaks and proper operation; determine necessary action;
  5. diagnose wheel bearing noises, wheel shimmy, and vibration concerns; determine necessary action;
  6. remove, clean, inspect, repack, and install wheel bearings and replace seals; install hub and adjust wheel bearings;
  7. check parking brake cables and components for wear, rusting, binding, and corrosion; clean, lubricate, or replace as needed;
  8. check parking brake operation; determine necessary action;
  9. check operation of parking brake indicator light system;
  10. check operation of brake stop light system; determine necessary action;
  11. replace wheel bearing and race;
  12. inspect and replace wheel studs;
  13. remove and reinstall sealed wheel bearing assembly;
  14. identify and inspect antilock brake system (ABS) components; determine necessary action;
  15. diagnose poor stopping, wheel lock-up, abnormal pedal feel or pulsation, and noise concerns caused by the antilock brake system (ABS); determine necessary action;
  16. diagnose antilock brake system (ABS) electronic control(s) and components using self-diagnosis and/or recommended test equipment; determine necessary action;
  17. depressurize high-pressure components of the antilock brake system (ABS);
  18. bleed the antilock brake system’s (ABS) front and rear hydraulic circuits;
  19. remove and install antilock brake system (ABS) electrical/electronic and hydraulic components;
  20. test, diagnose and service ABS speed sensors, toothed ring (tone wheel), and circuits using a graphing multimeter (GMM)/digital storage.
