Understanding Brake System Hydraulics

Which of the following is a key property of hydraulic fluid used in brake systems?

• High compressibility

• Low boiling point

• High viscosity

• Low compressibility

What is the primary function of the master cylinder in a hydraulic brake system?

• To increase the speed of the vehicle

• To convert mechanical force into hydraulic pressure

• To cool the brake pads

• To store hydraulic fluid

Which type of brake system typically provides better heat dissipation?

• Drum brakes

• Disc brakes

• Both provide equal heat dissipation

• Neither, as heat dissipation is not a concern

What is the main advantage of using disc brakes over drum brakes?

• Lower cost

• Easier to manufacture

• Better performance in wet conditions

• Longer lifespan

Which of the following is NOT a property of an ideal hydraulic fluid?

• High boiling point

• Non-corrosive

• High compressibility

• Low freezing point

In a hydraulic brake system, what happens when the brake pedal is pressed?

• Hydraulic fluid is compressed

• Hydraulic fluid is pressurized

• Hydraulic fluid is cooled

• Hydraulic fluid is released

Which component in a disc brake system is responsible for clamping the brake pads against the rotor?

• Master cylinder

• Brake caliper

• Brake drum

• Brake shoe

What is the role of the brake drum in a drum brake system?

• To house the brake pads

• To convert hydraulic pressure into mechanical force

• To act as a friction surface for the brake shoes

• To store hydraulic fluid

Which of the following equations represents the relationship between force, pressure, and area in a hydraulic system?

Why is it important for hydraulic fluid to have a high boiling point?

• To prevent freezing in cold conditions

• To ensure it remains liquid under high pressure

• To prevent vapor lock at high temperatures

• To increase the compressibility of the fluid
