STATE BRAKE CERTIFICATION
A cracked or torn vacuum diaphragm in a brake power booster would most likely cause: - ANSa
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: - ANSdrop
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? - ANSa plugged axle
The rear brakes are dragging after having new linings installed and the drums machined. the
most likely cause is the: - ANStechnician 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: - ANSbrake fluid or grease on the brake linings
Which of the following incorrect service procedures will cause brake lock-up? - ANSmaster
cylinder push rod adjusted too long
Which of the following incorrect service procedures could cause brake pedal pulsation? -
ANSincorrect run-out on the car brake lathe
A common cause of pedal pulsation during brake application is: - ANSNOT caused by
improperly torqued wheels, damaged backing plates, or lubricated shims
A properly functioning load sensing proportioning valve will: - ANScause 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. - ANSpump 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: -
ANSadjusted 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? - ANSsilicone fluid
added to the system
