Description
The front brake disc, also known as the brake rotor, is a critical component of a vehicle’s braking system. Here are some essential aspects about front brake discs:
- Function: The front brake discs work with the brake pads to slow or stop the vehicle. When the brake pedal is pressed, the brake pads clamp down on the rotor’s surface, creating friction that converts kinetic energy (motion) into thermal energy (heat), thus slowing the vehicle down.
- Material: Brake discs are typically made from cast iron due to its excellent heat dissipation properties. High-performance or racing vehicles may use carbon-ceramic discs for their superior heat resistance and reduced weight.
- Design: Brake discs come in various designs, including solid, vented, and drilled or slotted:
- Solid: Basic design, used in light-duty vehicles.
- Vented: Designed with internal vanes for better heat dissipation, used in heavier vehicles and performance cars.
- Drilled or Slotted: These designs improve cooling and performance by allowing gases and heat to escape more efficiently, reducing brake fade.
- Maintenance: Proper maintenance includes regular wear, scoring, or warping inspection. Signs of worn or damaged brake discs include vibration or pulsation felt through the brake pedal, squealing or grinding noises, or longer braking distances.
- Replacement: Brake discs should be replaced if they are worn beyond the manufacturer’s specifications or damaged. Replacement intervals vary based on driving habits, vehicle weight, and the type of disc material.
