Understanding Brake Booster Systems

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

• To increase the hydraulic pressure in the brake lines

• To amplify the force applied by the driver on the brake pedal

• To cool down the brake pads during braking

• To reduce the wear and tear of brake components

Which of the following is a common symptom of a failing brake booster?

• Squeaking noise when applying brakes

• Hard brake pedal

• Brake fluid leakage

• Overheating of brake pads

How can you test the performance of a brake booster?

• By checking the brake fluid level

• By measuring the vacuum pressure in the booster

• By inspecting the brake pads for wear

• By listening for unusual noises during braking

What is the typical vacuum source for a brake booster in a gasoline engine?

• Electric vacuum pump

• Engine intake manifold

• Hydraulic pump

• Turbocharger

Which of the following issues can cause a brake booster to malfunction?

• Low engine oil level

• Vacuum hose leak

• Worn-out brake pads

• Faulty alternator

What is the effect of a leaking brake booster diaphragm on braking performance?

• Increased braking efficiency

• Reduced braking force

• No effect on braking

• Enhanced pedal feel

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

• Brake caliper

• Master cylinder

• Vacuum hose

• Brake pedal

What is the role of the check valve in a brake booster system?

• To regulate brake fluid pressure

• To prevent vacuum loss when the engine is off

• To control the flow of brake fluid

• To adjust the brake pedal height

How does a vacuum leak in the brake booster affect engine performance?

• It improves fuel efficiency

• It causes the engine to stall

• It has no effect on the engine

• It increases engine power

What is the typical vacuum pressure range required for a brake booster to function effectively?

• 5-10 psi

• 15-20 inHg

• 25-30 psi

• 30-35 inHg
