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 - Answers-The correct answer is
C. The metering valve delays the flow of brake fluid to the
front calipers until the pressure in the system rises to a
point where the wheel cylinder can overcome the tension
of the brake shoe returning spring. The purpose is to have
both front and rear brakes apply simultaneously. This
prevents the front brakes from locking up during light
brake applications.
The driver of a vehicle with power disc/drum brakes says
that the brake pedal moved slowly to the floor while
,2|Page
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 - Answers-The
correct answer is A. if the primary piston cup in the master
cylinder is leaking, pressure will not build up ahead of the
primary piston to increase pressure to the rear brakes. The
piston will then move forward until the spring is
compressed enough to move the secondary piston.
Consequently, this internal leak will cause the brake pedal
to slowly drop to the floor.
What is the purpose of the master cylinder residual check
valve(s) on vehicles equipped with drum brakes?
A. Allowed 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 - Answers-The correct answer is B. Residual
check valve(s) are used on drum brakes to keep residual

low pressure (slight static pressure) in the brake system at
all times even when the brake pedal is released. This
pressure (5-20 psi) keeps the lips of the wheel cylinder
piston cups tight against the cylinder walls to prevent air
from entering the system when at rest (brakes released).
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 - Answers-
The correct answer is D. A metering valve requires a
minimum pressure (typically 75-125 psi) to open. At this
point pressurized fluid flows to the front calipers. Since the
bleeder tank is only pressurized to 25 psi, fluid pressure is
too low to open the metering valve during this procedure,
Therefore, when you use a pressure bleeder on a system
with a metering valve, you must manually keep the valve
open by either pushing the button in the end of the valve,
or pulling the stem outward on the end of the valve.

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.
Tech A says that too much rotor runout could be the
cause. Tech 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 - Answers-The correct answer is B.
Excessive rotor runout would cause a pulsating brake
pedal, but not uneven side-to-side pad wear. A frozen
caliper piston on the other hand, will keep both inner and
outer brake pads equally applied against the rotor even
when the brake pedal is released. This constant friction
will cause rapid pad wear in the affected caliper as well as
the front-end pull
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.
