Compared to the conventional gray cast iron brake discs, the highly durable HTCIC (High Tech Cast Iron Carbon) material is revolutionary, even ceramic brake discs are outperformed (responding qualities are present in both cold and hot condition). Further essential advantages are: Extremely high fading level, highest thermal stability possible, precise modulation as well as an affordable price. All our high performance brake parts are compatible with your car's safety features such as ABS, ESP, PSM, etc.

This kit consists of the following parts:

... for the front axle:
- Brake disc type drilled, front axle 410 x 26 mm left

What Do O-Brake Brake Discs Do?

Brake discs work together with brake pads and calipers to safely slow and stop your vehicle.

Core Functions:

  • Convert kinetic energy into controlled braking force.
  • Provide a stable friction surface for brake pads.
  • Dissipate heat generated during braking.
  • Maintain smooth, vibration-free braking response.

O-Brake discs are designed to perform reliably in everyday driving conditions, from cold starts to repeated urban braking.

Why Do Brake Discs Wear or Fail?

Brake discs are wear components and naturally degrade over time.

Common Causes of Wear or Failure Include:

  • Normal disc wear from repeated braking cycles.
  • Heat stress during frequent stop-start driving.
  • Surface corrosion caused by moisture and road salt.
