2026/2027 UPDATED STUDY GUIDE &
PRACTICE EXAM
A cracked or torn vacuum diaphragm in a brake power booster would most likely
cause: - correct answer-a hard pedal feel requiring very high pedal effort to stop
to test a vacuum power brake booster in the vehicle, you should pump the brake
pedal at least 4 times, hold the brake pedal depressed, and start the engine. the
brake pedal should: - correct answer-drop slightly and remain firm
A mechanic finds gear lube inside both rear drums on a rear wheel drive vehicle.
What is most likely the cause of this problem? - correct answer-a plugged axle
The rear brakes are dragging after having new linings installed and the drums
machined. the most likely cause is the: - correct answer-technician use the
parking brake to adjust shoes and the cable is stuck
While test driving a car, the mechanic finds that the right front brake "grabs". The
most likely cause of this problem is: - correct answer-brake fluid or grease on the
brake linings
Which of the following incorrect service procedures will cause brake lock-up? -
correct answer-master cylinder push rod adjusted too long
, Which of the following incorrect service procedures could cause brake pedal
pulsation? - correct answer-incorrect run-out on the car brake lathe
A common cause of pedal pulsation during brake application is: - correct answer-
NOT caused by improperly torqued wheels, damaged backing plates, or lubricated
shims
A properly functioning load sensing proportioning valve will: - correct answer-
cause an increase in the hydraulic pressure during braking at the rear wheel
cylinders when the vehicle is loaded.
which of the following is a quick way to isolated a defective master cylinder?
There are no external leaks in the system. - correct answer-pump up the brake
pedal, then hold it firm. if the pedal slowly drops to the floor, the master cylinder
may be defective.
After rebuilding a master cylinder, the rod between the master cylinder and
booster should be: - correct answer-adjusted properly
Upon inspecting brake fluid condition, the technician observes the diaphragm in
the master cylinder cup is swollen. Which of the following is the most likely
cause? - correct answer-silicone fluid added to the system
When inspecting brake fluid levels, a technician observes low fluid levels. which of
the following should be done first? - correct answer-Inspect disc brake pads for
excessive wear
