Brake components include rotors and slates. Which option best describes rotors and slates?

• A. Rotors and slates
• B. Pistons and cylinders
• C. Pads and calipers
• D. Discs and drums

Answer: (A)

The main idea here is recognizing the terminology used for brake components. Rotors are the discs that the brake pads clamp onto to slow the wheel. In the prompt, the two items being described are rotors and slates. The best choice is the one that uses the same two terms, rotors and slates, because it directly matches what the question states about the brake components.

Think of it this way: rotors are the discs, while the other options bring in components that aren’t the same pair or don’t describe a disc-based brake pairing. Pistons and cylinders relate to the hydraulic/engine side, pads and calipers describe parts that interact with the rotor but don’t name the exact pair, and discs and drums refer to different types of braking surfaces rather than the specific pair mentioned.
