	U	Disassemble and clean caliper assembly; inspect parts for wear, rust, scoring, and damage; replace seal, boot, and damaged or worn parts.
	V	Reassemble, lubricate, and reinstall caliper, pads, and related hardware; seat pads, and inspect for leaks.
	W	Adjust calipers with integrated parking brake system.
	X	Remove and replace rotor.
	Y	Diagnose wheel bearing noises, wheel shimmy, and vibration concerns; determine necessary action.
	Z	Remove, clean, inspect, repack, and install wheel bearings and replace seals; install hub and adjust wheel bearings.
	A	Check parking brake cables and components for wear, rusting, binding, and corrosion; clean, lubricate, and replace as needed.
	B	Check parking brake operation; adjust as needed.
	C	Check operation of parking brake indicator light system.
	D	Check operation of brake stop light system; adjust and service as needed.
	E	Replace wheel bearing and race.

7.	EVALUATION PROCEDURES:
	(A) There will be a written exam after each unit and a final, during the 7½ week term, during class time, and on announced dates. All will be weighted equally, except the final will count double.
	(B) There may be unannounced “pop” quizzes throughout the 7½ week term, which will also be weighted equally to other exams.
	(C) Routine evaluations will be made on an individual basis by the instructor during each lab session.
	(D) There will be a lab final (performance) exam. The score on this exam will be entered twice (doubled) when computing your final grade.
	(E) Grading will be weighted--30% of your grade for written assignments, 40% of your grade for lab assignments, 30% of your grade for tests. One grade point value will be deducted from total grade percentage for every hour absent.

Special Remarks:
1.	All announced examinations will be made up of multiple choice, completion and short essay type questions and will be given during regular class periods. Make-up exams will only be given if prior arrangements have been made.
2.	Attendance: College policy states that students may be dropped from enrollment when absent 20% of the scheduled class meetings. If enrolled from the beginning of the term, 15 hours will usually constitute 20% of a four-credit semester course which meets five hours per week. Reinstatement procedures are described in the PCC catalog.
3.	Tardy Policy: A student who is late three times (enters classroom after the instructor has taken roll) will be charged with one full absence unless the student can provide valid reasons for one or more of these tardies.
4.	Assignments/Missed Exams: It is the student's responsibility, whether present or absent, to obtain all material presented and to complete all course assignments. If prior arrangements are made or extenuating circumstances exist, makeup of tests may be allowed. Late homework papers will not be accepted unless those same extenuating circumstances exist. Makeup of quizzes is to be at the instructor's discretion.

9.	METHODS OF INSTRUCTION:
	To be successful in this course, students are expected to participate in discussions, readings, in-class writing, and peer review activities. The instructor may assign point values to such activities.
10.	ACADEMIC INTEGRITY:
	The very nature of higher education requires that students adhere to accepted standards of academic integrity. Therefore, Pueblo Community College has adopted a policy of academic conduct as described in the Student Handbook. Violation of academic integrity may be defined to include the following: cheating, plagiarism, falsification and fabrication, abuse of academic materials, complicity in academic dishonesty, and personal misrepresentation. It is the student’s responsibility to be aware of the behaviors that constitute academic dishonesty. Sanctions for violating the standards of academic integrity may include warning, probation, suspension, and/or failure of the course or assignment at the discretion of the instructor.
