Braking Basics

What is the role of friction in a braking system?

• Friction increases the speed of the vehicle

• Friction converts kinetic energy into thermal energy to slow down or stop the vehicle.

• Friction has no impact on the braking system

• Friction causes the vehicle to accelerate

Name two types of braking systems commonly used in vehicles.

• Caliper brakes

• Disc brakes, Drum brakes

• Hydraulic brakes

• Regenerative brakes

Why is brake fluid important in a braking system?

• Brake fluid cools down the engine

• Brake fluid improves fuel efficiency

• Brake fluid enhances the sound system

• Brake fluid transfers the force from the brake pedal to the brake components.

What are brake pads and shoes made of?

• Glass, Wood, Paper

• Friction materials like ceramic, semi-metallic, or organic compounds

• Concrete, Asphalt, Brick

• Rubber, Plastic, Metal

How often should the braking system be maintained?

• At least once a year or as recommended by the manufacturer or a qualified mechanic.

• Every 5 years

• Only when the brakes start making noise

• Once every 10,000 miles

Explain how friction helps in stopping a vehicle.

• Friction causes the vehicle to float above the road

• Friction has no impact on stopping a vehicle

• Friction increases the speed of the vehicle

• Friction creates resistance between the tires and the road surface, slowing down the rotation of the wheels when brakes are applied.

Discuss the differences between disc brakes and drum brakes.

• Drum brakes are more commonly used in modern vehicles compared to disc brakes.

• Disc brakes use calipers and rotors, while drum brakes use brake shoes and drums.

• Disc brakes are less efficient than drum brakes.

• Drum brakes use calipers and rotors, while disc brakes use brake shoes and drums.

What happens if there is air in the brake fluid?

• The brakes will work better

• Brake performance will be compromised.

• The car will go faster

• The brake fluid will evaporate

How do brake pads and shoes create friction to stop the vehicle?

• Brake pads and shoes create friction by attracting magnetic forces to stop the vehicle.

• Brake pads and shoes create friction by pressing against the brake rotors or drums when the brake pedal is pressed.

• Brake pads and shoes create friction by releasing air pressure in the brake system.

• Brake pads and shoes create friction by emitting heat when the brake pedal is pressed.

What are the signs that indicate the braking system needs maintenance?

• Decreased fuel efficiency

• Blinking headlights

• Strong smell of gasoline

• Squeaking or grinding noises, vibrating or pulsating brake pedal, longer stopping distances, brake warning light on the dashboard, soft or spongy brake pedal
