A brake disc, also known as a rotor, is a crucial component of modern disc brake systems. Here’s a breakdown of its significance:
What it does:
- Spins with the wheel.
- When you press the brake pedal, calipers squeeze friction-generating brake pads against the disc.
- The resulting friction slows down or stops the wheel.
Importance:
- Excellent stopping power: Discs excel in various conditions, particularly wet or muddy environments, due to their efficient heat dissipation.
- Consistent performance: Less heat buildup translates to more consistent braking behavior.
- Lighter weight: Compared to drum brakes, they contribute to better fuel efficiency and handling.
