Hydraulic Brake System

What is the purpose of a vehicle's brake system?

• To increase the speed of the vehicle

• To slow down the vehicle

• To steer the vehicle

• To provide power to the engine

How does a hydraulic brake system work?

• By using air pressure to slow down the vehicle

• By transmitting force through a liquid

• By using mechanical gears to slow down the vehicle

• By applying friction directly to the wheels

Why must hydraulic systems be free of air?

• Air can cause the brake system to overheat

• Air can cause the brake system to fail

• Air can compress and reduce the braking force

• Air can cause the brake fluid to evaporate

What happens when pressure is exerted on a liquid in a hydraulic system?

• The liquid expands and increases in volume

• The liquid compresses and decreases in volume

• The liquid changes its state from liquid to gas

• The liquid remains unchanged

Why is a hydraulic brake system divided into two circuits?

• To increase the braking force

• To reduce the braking distance

• To provide redundancy in case of a brake circuit failure

• To improve the vehicle's handling

How does a hydraulic system multiply forces?

• By increasing the size of the operating piston

• By decreasing the size of the working piston

• By using mechanical gears to amplify the force

• By using air pressure to increase the force

Why does brake fluid need to be exchanged regularly?

• To prevent the brake system from overheating

• To maintain the braking performance

• To reduce the risk of brake fluid leakage

• To improve the vehicle's fuel efficiency

Brake fluid is transported in a hydraulic brake system through (a)   .

• rubber hoses
• steel pipes
• plastic tubes
• electrical wires

Where are the rear axle brake pipes guided in a vehicle?

• Along the roof of the vehicle

• Along the sides of the vehicle

• Along the underbody of the vehicle

• Inside the engine compartment

What is the purpose of the brake servo in a hydraulic brake system?

• To increase the braking force

• To reduce the braking distance

• To provide power assistance for brake operation

• To prevent brake fluid from leaking
