Which are the two types of braking systems listed?

• A. Coaster brakes and Rim
• B. Drum brakes and Hydraulic
• C. Rim brakes and Disc brakes
• D. Drum brakes and Disc brakes

Answer: (C)

Bicycle braking systems come in two broad families: rim brakes and disc brakes. Rim brakes squeeze brake pads against the wheel rim to slow the bike, while disc brakes pull pads onto a rotor mounted at the hub for stopping power. This distinction matters for performance in different conditions and for compatibility with wheel and frame designs. The pair that reflects these two main systems is rim brakes and disc brakes. The other options mix hub-based brakes (like coaster or drum) with actuation methods (hydraulic), which aren’t the two primary system categories.
