Outcomes: The student will gain an understanding of the braking power assist unit along with diagnosis and repair.
- Test pedal free travel with and without engine running; check power assist operation.
- Check vacuum supply (manifold or auxiliary pump) to vacuum-type power booster.
- Inspect the vacuum-type power booster unit for vacuum leaks; inspect the valve check for proper operation; determine necessary action.
- Inspect and test the hydro-boost system and accumulator for leaks and proper operation; determine necessary action.
UNIT 6: Miscellaneous (Wheel Bearings, Parking Brakes, Electrical, Etc.) Diagnosis and Repair
Outcomes: The student will gain an understanding of the various ancillary systems and parts associated with the braking system, to include diagnosis, repair, and maintenance.
- Diagnose wheel bearing noises, wheel shimmy, and vibration concerns; determine necessary action.
- Remove, clean, inspect, repack, and install wheel bearings and replace seals; install hub and adjust wheel bearings.
- Check parking brake cables and components for wear, rusting, binding, and corrosion; clean, lubricate, or replace as needed.

Projects Required:
Various, refer to syllabus
Textbook:
Contact Bookstore for current textbook.
Attendance Policy:
Students should adhere to the attendance policy outlined by the instructor in the course syllabus.
Grading Policy:
The grading policy will be outlined by the instructor in the course syllabus.
Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
