Which of the following is a property of typical brake fluid used in automobile brake systems?
High boiling point
Low freezing point
Hygroscopic
Brake fluid is graded by the Department of Transportation on which of the following?

____________________ are used on drum brake systems to maintain brake fluid pressure and prevent air entry when the brakes are off.
Differential pressure switches
Residual pressure valves
Both
None of the above
Determining if brake fluid should be flushed can be done using which of the following methods?
Test strip
DVOM-galvanic reaction test
Time and mileage
With a ______________________ in the brake system, any fluid leak could mean the whole braking system fails.
tandem master cylinder
single-piston master cylinder
quick take-up master cylinder
None of the above
What type of master cylinder is used in a typical anti-lock braking system divided brake system?
tandem master cylinder
single-piston master cylinder
quick take-up master cylinder
None of the above
True or False. To ensure that a leak in one brake circuit will not affect the other circuit, master cylinder reservoirs have two separate chambers.
true
false
Most modern master cylinder reservoirs are equipped with a low brake fluid float switch that turns on the __________________ on the instrument panel and/or sets a notification on the driver information system.
amber brake warning light
yellow brake warning light
red brake warning light
None of the above
___________________ carry brake fluid from the master cylinder to the brake units.
Double-walled steel lines only
Rubber hoses only
Doubled-walled steel lines and rubber hoses
none of the above
Brake hoses should never be?
Pinched
Kinked
Bent tighter than a specific radius
all the above
True or False. Many brake hoses use banjo fittings to connect the hose to the wheel unit.
true
false
Banjo-type fittings typically include?
Banjo fitting
Banjo bolt
Two copper or aluminum washers
all the above
The proportioning valves used in typical brake systems can be:
pressure-sensitive.
load-sensitive.
both
none of the above
Which of the following can turn on the brake warning light?
Parking brake being engaged
Brake fluid level being low
Pressure being unequal in the brake system
Which of the following is a typical brake system warning light switch location?
Parking brake assembly
Pressure differential assembly
Master cylinder reservoir
All of the following are methods used to force air and contaminated fluid out of a brake system in a vehicle, EXCEPT:
vacuum bleeding.
pressure bleeding.
bench bleeding.
manual brake bleeding.
The quick take-up valve on a quick take-up master cylinder regulates fluid flow:
between the master cylinder and the reservoir.
between the reservoir and the pushrod.
between front and back wheels.
between the two hydraulic circuits of the system.
