About This Quiz

When purchasing brake rotors, there are several different types from which to choose. For example, there are driller brake rotors, slotted brake rotors, performance brake rotors and more. How knowledgeable are you when it comes to brake rotors?
Which of the following is a major type of brake rotor?
Drilled brake rotor
Slotted brake rotor
All of the above
There are two major types of high-performance brake rotors -- drilled and slotted.How Brake Rotors Work

Which type of brake rotors have holes?
Drilled brake rotors
Drilled brake rotors, as the name implies, have holes drilled in them. How Brake Rotors Work
Slotted brake rotors
All of the above

Why do drilled brake rotors have holes?
To help dissipate heat
To help eliminate gas built up
All of the above
Drilled brake rotors have holes for two reasons. The first is heat. When the brake pad grabs the rotor, it creates friction, which creates heat. If that heat can't escape, it leads to brake fade, which reduces the brakes' stopping power. The second reason is gas build up. How Brake Rotors Work

High-performance brake rotors are usually:
Slotted
When you're talking about high performance rotors, slotted, not drilled, rotors are the choice of most racers. How Brake Rotors Work
Drilled
Polished

What is the downside to using drilled rotors?
The holes weaken the rotors
The holes cause the rotors to rust
The downside of using drilled rotors on your vehicle is that all of those holes tend to weaken the rotors -- just like punching holes in the wall of a house would weaken the wall. After repeated stressful driving, the rotors can even crack. How Brake Rotors Work
Debris gets stuck in the holes

What is the problem with using slotted brake rotors for high-performance braking?
They wear down the brake pads faster than other rotors
Slotted brake rotors are great for high-performance braking; however, you'd better be ready to change the brake pads more often. How Brake Rotors Work
They crack easily
They over-heat easily

Most common street motorcycles use which type of brake rotor?
Drilled
Most street driven motorcycles come equipped with drilled brake rotors. How Brake Rotors Work
Slotted
None of the above

Most high-performance motorcycles use which type of brake rotor?
Drilled
Slotted
Most high-performance or on-track bikes will typically use slotted rotors. How Brake Rotors Work
None of the above

Brake rotors on trucks are typically:
Heavier than other brake rotors
Larger than other brake rotors
All of the above
Because trucks are so big and heavy, their brake rotors need to be larger and more powerful to compensate for the extra stress. How Brake Rotors Work

What is the main function of a brake caliper?
To apply pressure to the brake pad
Brake calipers play a vital role in a vehicle's braking system because they apply pressure to the brake pads, which, in turn, apply pressure to the brake rotors to slow or stop the vehicle. How Brake Rotors Work
To control the flow of brake fluid
To control the brake lines
