• Master cylinder

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?

• Color

• pH value

• How much water it can hold

• All of the above

____________________ 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

• 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
