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? - ✔✔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? - ✔✔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 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 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? -
✔✔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? - ✔✔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 D is correct. A worn wheel bearing
will cause a growl that increases with vehicle speed.
