A vehicle pulls left after the brake pedal is released. This is caused by:
a. a restricted left front brake hose
b. a cut master cylinder piston seal
c. a faulty metering valve
d. a restricted right front brake hose ---------- Correct Answer ------------ A : a restricted left front
brake hose
why : a restricted left front brake hose would allow higher pressure from the master cylinder to
get to the caliper, but not leave the caliper. this condition would leave the left front caliper
,applied after the brake pedal is released

fades under light pressure
indicates:
a. A brake line restriction
b. Spring tension on the
brake pedal is weak
c. Internal leaks
d. The system is operating
properly ---------- Correct Answer ------------ c

fluids, contain a purple dye
c. Polyglycol brake fluids are
amber to clear in color
d. All DOT approved brake
fluids are hygroscopic ---------- Correct Answer ------------ d

can be detected by the:
a. Internal leak test
b. External leak test
c. Compensating port test
d. QTU test ---------- Correct Answer ------------ a
Honing will remove the anodized
finish on which type of
master cylinder?
a. Add-on ABS
b. Aluminum
c. Cast iron
d. Composite ---------- Correct Answer ------------ b

size by a specified amount
d. Have scoring no deeper
than 0.006 inch (0.15 mm) ---------- Correct Answer ------------ b
The first component in a brake
system bleeding sequence is
the:
a. Master cylinder
b. Wheel cylinder
c. Combination valve
, d. Proportioning valve ---------- Correct Answer ------------ a
Generally speaking, which of
the wheel brakes should you
bleed first?
a. The one farthest from the
master cylinder
b. The one closest to the
master cylinder
c. The one closest to the
driver
d. The one closest to the
passenger ---------- Correct Answer ------------ a
What special tool is required
to pressure bleed a system
equipped with a metering
valve?
a. An adjustment gauge
b. A torque wrench
c. A vacuum tool
d. An override tool ---------- Correct Answer ------------ d
