ASE A5 Practice Test/90 Questions with Answers A+ Graded

• On a car with disc/drum brakes, the front brakes grab

quickly when light pedal pressure is applied. This problem

could be caused by a bad:

• proportioning valve
• pressure safety switch
• metering valve
• residual check valve - -C

-2. The driver of a vehicle with power disc/drum brakes says that the brake pedal moves slowly to the floor while maintaining pedal pressure at a stoplight. What could cause this problem?

• leaking primary piston cup in master cylinder
• leaking power brake booster
• leaking residual check valve in master cylinder
• internal leak in the combination valve - -A

-3. Which of the following would MOST LIKELY happen if the measurements taken from the check shown above varied from the manufacturer's specifications?

• noisy brake operation
• brake grab or pull
• pulsating brake pedal
• low brake pedal - -C

-4. What is the purpose of the master cylinder residual check valve(s) on vehicles equipped with drum brakes?

• allows the driver to pump up the brakes
• prevents air from entering the hydraulic system
• prevents wheel lockup by reducing the hydraulic

pressure

• reduces pedal pulsation by controlling hydraulic

pressure - -B -5. A technician has just overhauled the front brakes on a vehicle with front disc and rear drum brakes. However, when he attaches a pressure bleeder (pressurized to about 25 psi) to the master cylinder, he cannot get any fluid to come out of the disc brake caliper bleeder screws. Which of the following is MOST LIKELY the cause?

• bad proportioning valve 1 / 3

• bad pressure differential valve
• proportioning valve release button not activated
• metering valve release button not activated - -D

-6. On a vehicle with single piston floating caliper front disc brakes, the brake pads on the left side of the vehicle are almost completely worn while the right side is almost new.Technician A says that too much rotor runout could be the cause. Technician B says that a binding caliper piston could be the cause. Who is right?

• Technician A only
• Technician B only
• Both A and B
• Neither A or B - -B

-7. What is the purpose of the bar that is being removed from the brake assembly shown below?

• to equalize the braking force between the shoes

during normal braking

• to center the shoes after each brake application
• to force the shoes into the drum when the parking

brakes are applied

• to reduce the distance between the shoes and the

drum - -C -8. A hydraulic brake line is leaking. Which of the following is the correct repair procedure?

• Cut out the bad section and replace with new steel

tubing using compression fittings.

• Replace the leaking line with double-flared, seamless

copper tubing.

• Cut out the bad section and replace with single-flared

steel tubing using flare nuts and unions.

• Replace the leaking line with double-flared steel

tubing. - -D

-9. The set-up shown above is used to check: (dial indicator on rotor face)

• rotor parallelism
• wheel bearing adjustment
• rotor lateral runout
• rotor face wear - -C

-10. Which of the following problems would be caused by using a residual check valve in a disc brake master cylinder?

• reduced brake pedal travel
• reduced brake system pressure 2 / 3

• increased brake pad wear
• increased rotor runout - -C

-11. A customer complains that their vehicle pulls to the right when the brakes are applied. Technician A says a restricted brake line to the left caliper can cause this problem. Technician B says a malfunctioning proportioning valve is probably the cause. Who is right?

• Technician A only
• Technician B only
• Both A and B
• Neither A or B - -A

-12. With foot pressure applied, the brake pedal on a vehicle with vacuum assisted power brakes moves down slightly when the engine is started. Technician A says that this condition can be caused by a leaking power brake booster diaphragm. Technician B says that the cause could be a faulty power brake booster check valve. Who is right?

• Technician A only
• Technician B only
• Both A and B
• Neither A or B - -D

-13. Technician A says that the tool shown above is used to adjust the brake shoes. Technician B says that the tool shown above is used to determine the inside diameter of the drum. Who is right?

• Technician A only
• Technician B only
• Both A and B
• Neither A or B - -A

-14. The hydraulic system on a vehicle with integral ABS is to be bled. Technician A says that the front brakes can be bled in a conventional manner. Technician B says that both front and rear brakes can only be bled using the pressure from a fully charged accumulator. Who is right?

• Technician A only
• Technician B only
• Both A and B
• Neither A or B - -A

-15. A driver complains that the ABS system on his car engages every time he applies the brakes on a cobblestone roadway he uses going back-and-forth to work. This
