ASE A5 Practice Test
1. 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:
A. proportioning valve
B. pressure safety switch
C. metering valve
D. residual check valve – answer 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?
A. leaking primary piston cup in master cylinder
B. leaking power brake booster
C. leaking residual check valve in master cylinder
D. internal leak in the combination valve - answerA
3. Which of the following would MOST LIKELY happen
if the measurements taken from the check shown above
varied from the manufacturer's specifications?
A. noisy brake operation
B. brake grab or pull
C. pulsating brake pedal
D. low brake pedal - answerC
4. What is the purpose of the master cylinder residual
check valve(s) on vehicles equipped with drum brakes?
A. allows the driver to pump up the brakes
B. prevents air from entering the hydraulic system
C. prevents wheel lockup by reducing the hydraulic
pressure
D. reduces pedal pulsation by controlling hydraulic
pressure - answerB
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?
A. bad proportioning valve
,B. bad pressure differential valve
C. proportioning valve release button not activated
D. metering valve release button not activated - answerD
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?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - answerB
7. What is the purpose of the bar that is being removed
from the brake assembly shown below?
A. to equalize the braking force between the shoes
during normal braking
B. to center the shoes after each brake application
C. to force the shoes into the drum when the parking
brakes are applied
D. to reduce the distance between the shoes and the
drum - answerC
8. A hydraulic brake line is leaking. Which of the following is
the correct repair procedure?
A. Cut out the bad section and replace with new steel
tubing using compression fittings.
B. Replace the leaking line with double-flared, seamless
copper tubing.
C. Cut out the bad section and replace with single-flared
steel tubing using flare nuts and unions.
D. Replace the leaking line with double-flared steel
tubing. - answerD
9. The set-up shown above is used to check: (dial indicator on rotor face)
A. rotor parallelism
B. wheel bearing adjustment
C. rotor lateral runout
D. rotor face wear - answerC
10. Which of the following problems would be caused by
using a residual check valve in a disc brake master cylinder?
A. reduced brake pedal travel
B. reduced brake system pressure
, C. increased brake pad wear
D. increased rotor runout - answerC
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?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - answerA
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?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - answerD
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?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - answerA
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?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - answerA
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
