Hydraulic Brake System Quiz

What is the primary function of brake fluid in a hydraulic braking system?

• Lubricate brake pads

• Transfer heat from the rotors

• Multiply force and transmit motion

• Prevent corrosion in calipers

Which of the following best describes a key property of brake fluid?

• Compressible under pressure

• Changes viscosity quickly

• Incompressible in a closed system

• Evaporates to reduce heat

What principle explains how pressure applied to liquid in a confined space transfers equally in all directions?

• Bernoulli’s Principle

• Newton’s Third Law

• Pascal’s Law

• Boyle’s Law

Why is air considered a problem in hydraulic brake systems?

• It increases boiling point

• It reduces the amount of fluid needed

• It compresses under pressure, reducing efficiency

• It increases system pressure

What allows a hydraulic system to increase or decrease motion or force?

• Brake rotor thickness

• Type of brake fluid

• Different sized pistons

• Amount of friction material

Which part of the brake system is responsible for creating hydraulic pressure?

• Brake booster

• Master cylinder

• Wheel cylinder

• Brake caliper

What does the term “braking ratio” refer to?

• Balance of heat between front and rear pads

• The comparison of front-to-rear braking force

• Ratio of fluid used during each brake cycle

• Brake pad thickness front versus rear

During braking, why does the front of a vehicle typically receive more braking force?

• Rear tires are more durable

• Air resistance affects the front more

• Weight shifts to the front wheels

• ABS only controls the front

If a truck is carrying a heavy load in the back, what happens to the brake ratio?

• It shifts toward the front

• It remains unchanged

• It shifts toward the rear

• It becomes unstable

What component helps manage changes in brake ratio during different load conditions?

• Brake fluid reservoir

• Load-sensing proportioning valve

• Wheel speed sensor

• Vacuum booster
