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? - 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? - 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. - 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. - 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? -
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? - 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. - 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
