Welcome to the basic trivia quiz on the automobile brake system. The system is an essential part of an automobile as it not only helps them stop, but it also helps to prevent a vehicle from losing control in slippery surfaces. This quiz is to determine if the test taker has a basic knowledge of an automotive brake system. Give it a shot!

### What produces hydraulic pressure in a brake system?

• A.

Caliper

• B.

Wheel Cylinder

• C.

Master Cylinder

• D.

C. Master Cylinder
Explanation
The master cylinder is responsible for producing hydraulic pressure in a brake system. It is a component that converts the force applied to the brake pedal by the driver into hydraulic pressure. When the brake pedal is pressed, it pushes a piston inside the master cylinder, which in turn forces brake fluid through the brake lines to the calipers or wheel cylinders. This hydraulic pressure is what ultimately causes the brake pads to clamp down on the rotors or drums, resulting in the vehicle coming to a stop.

### How many wheel cylinders does a four-wheel disc brake system have

• A.

2

• B.

4

• C.

1

• D.

0

D. 0
Explanation
A four-wheel disc brake system does not have any wheel cylinders. In a disc brake system, the braking force is applied by calipers that squeeze brake pads against a rotor to slow down or stop the vehicle. Wheel cylinders are part of a drum brake system, which is a different type of braking system used in some vehicles. In a drum brake system, wheel cylinders are used to apply the brake shoes against the drum to create friction and slow down or stop the vehicle.

### Wheel cylinders are used on ________ brakes.

drum
Explanation
Wheel cylinders are used on drum brakes. Drum brakes are a type of braking system where the brake shoes are located inside a drum that rotates with the wheel. When the brake pedal is pressed, hydraulic pressure is applied to the wheel cylinders, causing the brake shoes to expand and press against the inner surface of the drum, creating friction and slowing down the rotation of the wheel. This design is commonly used in older vehicles and some heavy-duty applications.

### Disc brakes use

• A.

Brake shoes

• B.

Wheel cylinders

• C.

• D.

Cones

Explanation
Disc brakes use brake pads, not brake shoes, wheel cylinders, or cones. Brake pads are the components of disc brakes that come into contact with the rotor to create friction and slow down or stop the vehicle. They are typically made of a high-friction material, such as ceramic or metal, and are designed to withstand high temperatures and provide consistent braking performance. Brake pads are essential for the proper functioning of disc brakes and are a crucial part of the braking system in most modern vehicles.

### What is the process of getting air out of the brake lines?

• A.

Bleeding

• B.

Air purging

• C.

Air blowing

A. Bleeding
Explanation
The process of getting air out of the brake lines is called bleeding. Bleeding involves removing any air bubbles that may have entered the brake lines, which can cause a loss of brake pressure and reduced braking efficiency. This is typically done by opening the bleeder valves on each brake caliper or wheel cylinder and allowing the air to escape while fresh brake fluid is pumped through the system. Bleeding the brake lines helps to ensure that the brakes function properly and provide reliable stopping power.
