The Disc Rotor (also called Brake Disc) is a key component of a vehicle’s braking system.
🔧 Description:
It is a round, flat metal disc attached to the wheel hub.
Works with brake pads and calipers in a disc brake system.
Typically made of cast iron, carbon composite, or steel for high heat resistance.
✅ Functions:
Provides a surface for brake pads to clamp on, generating friction to stop the vehicle.
Converts kinetic energy into heat during braking.
Ensures smooth, controlled stopping performance.
Helps maintain consistent braking efficiency under various driving conditions.
⚠️ Symptoms of a Worn or Faulty Disc Rotor:
Vibrations or pulsations when braking.
Squealing or grinding noises during braking.
Visible grooves, scoring, or warping on the rotor surface.
Reduced braking efficiency or longer stopping distances.
🚗 Importance:
A high-quality disc rotor is essential for safe, reliable, and efficient braking. Worn or damaged rotors can compromise vehicle control and safety.
