Brake components are described as which of the following?

• A. Rotors and slates
• B. Pistons and cylinders
• C. Pads and calipers
• D. Shafts and bearings

Answer: (A)

Brake components are described by the parts that create the friction and apply it. In a disc brake, braking happens when friction material (pads) is pressed against a rotating surface (the rotor) by a clamping mechanism (the calipers). The pads provide the friction, and the calipers (often with pistons) push those pads onto the rotor to slow the wheel. Among the options, the pair that best represents the mechanism is pads and calipers because it captures both the friction surface and the means of applying it. The other choices either point to parts that aren’t typically described together as the braking components, or use terms that aren’t standard for brakes (for example, “slates” isn’t a recognized brake component).
