Quiz on Vehicle Brakes

What is the primary function of brakes in vehicles?

• To accelerate the vehicle

• To slow down and stop vehicles in a controlled way

• To signal other drivers

• To change the direction of the vehicle

Aside from stopping a vehicle, what is another function of brakes?

• To keep the vehicle stationary once it has stopped moving

• To play music inside the vehicle

• To improve fuel efficiency

• To activate the airbags

Which technologies are incorporated in brake systems?

• Mechanical, hydraulic, and solar

• Mechanical, pneumatic, and electrical

• Mechanical, hydraulic, and electrical

• Mechanical, nuclear, and hydraulic

What happens when a smaller output piston is used in a hydraulic system, as per the image?

• It gives a larger force and more travel.

• It gives the same force and the same travel.

• It gives a smaller force but more travel.

• It gives a larger force but less travel.

What is an example of a hydraulic system?

• Bicycle pump

• Car engine

• Floor jack

• Electric motor

What links the force and motion from the piston in the cylinder to lift the load in a hydraulic system?

• Air

• Fluid

• Gears

• Springs

What occurs when the lever is raised in a simple hydraulic system?

• The outlet check valve opens and the inlet check valve closes

• The outlet check valve closes and the inlet check valve opens

• Both the inlet and outlet check valves open

• Both the inlet and outlet check valves close

Two pistons are connected by a hydraulic line. If the input piston is larger than the output piston, what is the effective force and movement of the output piston compared to the input?

• The force will be less, and so will the movement

• The force will be more, but the movement will be less

• The force will be less, but the movement will be more

• Both the force and the movement will be more

If the input piston is larger than the output piston, what is the effective force and movement of the output piston compared to the input piston?

• The force will be less, and so will the movement

• The force will be more, but the movement will be less

• The force will be less, but the movement will be more

• Both the force and the movement will be more

What does a master hydraulic cylinder do in a brake system?

• It pumps air into the brake lines.

• It converts the force from the brake pedal into pressure in the brake line fluid.

• It cools down the brake fluid.

• It increases the brake pedal resistance.
