Understanding Automotive Brake Systems

What is the primary function of a disc brake system in an automobile?

• To increase the speed of the vehicle

• To slow down or stop the vehicle

• To enhance fuel efficiency

• To improve aerodynamics

Which component of the disc brake system is responsible for squeezing the brake pads against the disc?

• Brake rotor

• Brake caliper

• Brake drum

• Brake pedal

In a drum brake system, what is the role of the brake shoes?

• To rotate the drum

• To press against the drum to create friction

• To cool down the brake system

• To lubricate the drum

Which of the following materials is commonly used for manufacturing brake pads due to its high friction properties?

• Plastic

• Asbestos

• Rubber

• Wood

What is the main advantage of using ceramic brake pads over metallic ones?

• Lower cost

• Better performance in wet conditions

• Quieter operation and less dust

• Higher thermal conductivity

Which component in a drum brake system helps return the brake shoes to their original position after braking?

• Brake drum

• Return springs

• Wheel cylinder

• Brake pedal

What is the primary disadvantage of using asbestos in brake pads?

• High cost

• Poor friction properties

• Health hazards due to dust

• Low durability

In a disc brake system, what is the purpose of the brake rotor?

• To provide a surface for the brake pads to press against

• To house the brake fluid

• To connect the brake pedal to the caliper

• To cool the brake system

Which of the following is NOT a typical material used for brake pads?

• Semi-metallic

• Organic

• Ceramic

• Glass

What is the main function of the wheel cylinder in a drum brake system?

• To rotate the wheel

• To apply hydraulic pressure to the brake shoes

• To cool the brake system

• To measure the speed of the vehicle
