Automotive Final Exam – Brake Systems & Electrical

The main difference between service brakes and parking brakes is:

• Service brakes are used for stopping the vehicle while driving, while parking brakes are used to keep the vehicle stationary when parked.

• Service brakes are only used when parking, while parking brakes are used while driving.

• Service brakes and parking brakes are the same and can be used interchangeably.

• Service brakes are used for emergency stopping only, while parking brakes are used for normal stopping.

When the brake pedal is pressed, it activates which component first?

• Master cylinder

• Brake pads

• Brake drum

• Brake fluid

Brake fluid flows from the master cylinder to:

• the brake calipers

• the radiator

• the fuel tank

• the exhaust pipe

Disc brakes stop a vehicle by:

• creating friction between brake pads and a disc

• increasing the speed of the wheels

• reducing the engine power

• inflating the tires

What does ABS stand for?

• Anti-lock Braking System.

• Automatic Braking System.

• Advanced Brake Safety.

• Active Balance Suspension.

The purpose of the ABS system is:

• To prevent wheel lock-up during braking

• To increase engine power

• To improve fuel efficiency

• To reduce tire wear

ABS brakes work by:

• Locking the wheels during braking

• Pulsing the brakes to prevent wheel lockup

• Increasing the speed of the vehicle

• Reducing the effectiveness of the brakes

When ABS is activated, the driver typically feels what in the pedal?

• A smooth, steady pressure

• A pulsating or vibrating sensation

• No change at all

• The pedal becomes very hard

Drilling or slotting a rotor allows which of the following to escape?

• Heat

• Water

• Air

• Oil

Brake fade is:

• A sudden increase in braking power

• A reduction in braking effectiveness due to overheating

• A type of brake fluid

• A method of brake adjustment
