ASE A5 BRAKES EXAM NEWEST ACTUAL EXAM COMPLETE 240 QUESTIONS
AND CORRECT DETAILED ANSWERS/NEWEST UPDATE!!!
A vehicle with ABS anti-lock brakes has an audible clicking noise when it is first started. The
noise goes away after a few seconds. Technician A says this is one of the hydraulic valves in the
hydraulic valve assembly sticking. Technician B says this is a normal condition. Who is correct?
- (Correct Answer)-TECH B is correct. The ABS system runs a system check when the key is
first turned to the ON position. The valves sometimes make a clicking noise during this check.
A hydro-boost brake system has reduced braking performance. Technician A says to check the
power steering system. Technician B says to check the vacuum check valve. Who is correct? -
(Correct Answer)-TECH A is correct. The power steering pump produces pressure for the Hydro-
Boost unit.
A vehicle with power assisted brakes has a hard brake pedal. Which of the following is LEAST
likely to cause this condition?
A. Master cylinder.
B. Vacuum check valve.
C. Brake booster.
D. Low manifold vacuum. - (Correct Answer)-Answer A is correct. Faulty master cylinders do
not typically result in a hard brake pedal. Actually it's more common for a faulty master cylinder
to cause a low brake pedal that fades to the floor as it is applied. This is the least likely
component listed to result in a hard brake pedal.
A vehicle pulls to the left only when the brakes are applied. This condition is MOST likely
caused by:
A. A seized left front caliper.
B. A restriction in the left front brake line.
C. Leaking master cylinder cup seals.
D. A seized right front caliper. - (Correct Answer)-Answer D is correct. A frozen right front
caliper will cause the vehicle to pull to the left when braking.

Technician A says accumulators are found only on non-integral ABS systems. Technician B says
some integral ABS units contain high pressure accumulators that must be discharged before
repair. Who is correct? - (Correct Answer)-TECH B is correct. High pressure units can be
dangerous and must be discharged before removal. Always check with manufacturer's procedures
before disassembling an ABS unit
Technician A says ABS control units are programmed to ignore speed sensor input variations
below a certain threshold. Technician B says a one-channel ABS system controls hydraulic
pressure to the rear brake units. Who is correct? - (Correct Answer)-Both technicians are correct.
A vehicle's right front wheel has a growl that increases with vehicle speed. The MOST likely
cause is:
A. Excessive rotor lateral run out.
B. Warped rear brake drums.
C. Worn CV-Joint.
D. Worn wheel bearing. - (Correct Answer)-Answer D is correct. A worn wheel bearing will
cause a growl that increases with vehicle speed.
Two technicians are discussing master cylinder residual check valves. Technician A says the
check valve is used on four wheel disc brake systems. Technician B says the valve maintains
pressure when the brakes are released. Who is correct? - (Correct Answer)-Technician B is
correct. The constant low pressure, usually 6 psi to 8 psi keeps air from entering the wheel
cylinders.
The brake pad wear indicator light is illuminated on the instrument panel. Technician A says this
is because the brake pads have become contaminated. Technician B says this is the pad wear
sensor contacting the brake rotor. Who is correct? - (Correct Answer)-TECH B is correct. When
the sensors tip contacts the rotor, the pad warning light illuminates on the instrument panel.
The rear wheels of a vehicle are locking up only when the brakes are applied. This is caused by a
faulty:
A. Metering valve.
