The two major components of a disc brake are the?

• A. Brake pad and piston
• B. Caliper and disc
• C. Cooling fins and disc
• D. Disc and brake pad

Answer: (B)

The two major components of a disc brake are the caliper and the disc. The caliper is the assembly that houses the brake pads and the piston, which applies the pressure to the pads when the brakes are engaged. The disc, also known as the rotor, is the circular metal component that rotates with the wheel and is clamped by the brake pads when braking occurs. This design allows for efficient heat dissipation and effective stopping power, making disc brakes essential for vehicle safety and performance. The other options, while mentioning components related to the braking system, do not accurately represent the two primary parts that work together in the disc brake mechanism. For instance, focusing solely on the brake pad and piston overlooks the vital role of the caliper as part of the system. Thus, the selection of caliper and disc reflects a comprehensive understanding of the mechanics involved in disc braking systems.
