CDX Brake System Quiz

Braking applications produce large amounts of heat, so the brake fluid used ________.

• Must be nonflammable

• Must have a high boiling point

• Must help to cool down the brakes

• Must cool down with water added

In vehicles with an electronic brake proportioning function, the pressure reduction is handled electronically and can compensate for differences in traction by monitoring wheel _______.

• Slip

• Friction

• Size

• Pressure

The valve that reduces rear brake pressure when the vehicle is lightly loaded and allows higher pressure when it is heavily loaded is:

• load-sensitive proportioning valve.

• metering valve.

• pressure differential valve.

• combination valve.

Standard brake fluid is hygroscopic, which means it __________.

• Has a high boiling point

• Has a low boiling point

• Readily absorbs water

• Does not absorb water

A _______ master cylinder is used in a typical anti-lock braking system.

• Tandem

• Single-piston

• Non-piston

• Triple-piston

Applying the brakes firmly will cause the pressure to ________, and the spring returns the pressure differential valve to center.

• Decrease

• Equalize

• Increase

• Remain unchanged

This type of flare is sometimes called a bubble flare:

• International Standards Organization (ISO) flare

• Inverted double flare

• Inverted single flare

• Rounded flare

Most modern master cylinder reservoirs are equipped with a low brake fluid level float switch that turns on the ________light on the instrument panel and/or sets a notification on the driver information system.

• Check engine

• TPMS warning

• Brake warning

• Electrical problem warning

________ 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

• Compensating ports

• Inlet ports

For most of their length, brake lines are ________, coated to resist corrosion, and attached to the body with clips or brackets to minimize damage from vibration.

• Triple-walled aluminum

• Double-walled aluminum

• Triple-walled steel

• Double-walled steel
