Understanding Brake Boosters

What is the primary function of a brake booster in a vehicle's braking system?

• To increase the engine's horsepower

• To reduce the effort needed to apply the brakes

• To enhance the vehicle's fuel efficiency

• To improve the vehicle's suspension system

Which type of brake booster uses engine vacuum to assist in braking?

• Hydraulic brake booster

• Electric brake booster

• Vacuum brake booster

• Pneumatic brake booster

What is a common symptom of a failing brake booster?

• Increased fuel consumption

• Hard brake pedal

• Overheating engine

• Squealing noise from the brakes

Which of the following is NOT a type of brake booster?

• Vacuum brake booster

• Hydraulic brake booster

• Electric brake booster

• Magnetic brake booster

How does a vacuum brake booster assist in braking?

• By using hydraulic pressure

• By using electric motors

• By using vacuum pressure

• By using magnetic fields

What might you experience if a brake booster fails while driving?

• The vehicle accelerates unexpectedly

• The brake pedal becomes very easy to press

• The brake pedal becomes very hard to press

• The steering wheel becomes difficult to turn

Which component is directly connected to the brake booster to provide assistance?

• Brake caliper

• Brake pedal

• Brake rotor

• Brake fluid reservoir

What is the main advantage of an electric brake booster over a vacuum brake booster?

• It is cheaper to manufacture

• It provides consistent assistance regardless of engine vacuum

• It requires more maintenance

• It is heavier and bulkier

Which of the following could be a cause of brake booster failure?

• Low engine oil

• A vacuum leak

• A faulty alternator

• Worn-out brake pads

What is the role of the diaphragm in a vacuum brake booster?

• To store brake fluid

• To create a vacuum seal

• To convert vacuum pressure into mechanical force

• To regulate brake fluid pressure
