Brake discs are essential components of a vehicle's braking system, providing the surface against which brake pads clamp to slow down or stop the vehicle. Typically made from cast iron, they can also be found in materials such as carbon composite or aluminum for performance applications. Brake discs work by converting kinetic energy into thermal energy through friction, which is generated when the brake pads press against the disc during braking.
| Material | Cast iron, carbon composite, or aluminum |
| Diameter range | 240 mm to 400 mm |
| Thickness range | 20 mm to 30 mm |
| Type | Solid, vented, or slotted |
| Weight | 3 kg to 10 kg |
When selecting brake discs, buyers should consider the vehicle type and intended use, as performance requirements can vary significantly. It is important to specify the correct diameter and thickness for compatibility with existing brake systems. Additionally, buyers may want to inquire about material options based on performance needs, such as heat resistance or weight considerations. Certifications and standards should also be verified to ensure quality and safety.

Signs include vibration during braking, noise, and reduced braking performance.
Typically, brake discs should be inspected every 20,000 to 30,000 miles, but replacement depends on wear.
Yes, but ensure they are compatible with your vehicle's braking system.
Vented discs have internal cooling channels for better heat dissipation, making them suitable for high-performance applications.
Many manufacturers offer warranties, typically ranging from 1 to 3 years, depending on the product.
If the pads are worn down to the minimum thickness or if they show signs of damage, they should be replaced.
