Formula:R Brake Pads – for your perfect braking point. 

Compound Type:

OZ 20: suitable for long distance series; extremely high stability of the friction coefficient over a wide temperature range
OZ 30: suitable for sprint distances; highest friction coefficient with good wear properties of brake disc and brake pad

The mixtures of the friction material of Formula:R brake pads are individually developed in cooperation with our racing team and are successfully tested in endurance racing. The durability of brake discs and brake pads are just as important as a stable friction coefficient, which ensures that the pads are extremely fading-resistant. To adapt the pads to the individual requirements of different drivers, different friction compounds are available for some applications.

Zimmermann has been manufacturing high-quality brake parts at the Sinsheim site for more than 60 years. Our brake parts are used successfully in the Nürburgring Endurance Series (NLS) under the extreme conditions at the Nürburgring and are constantly being further developed.

About Replacement for Ceramic Disc

Replacement for Ceramic Discs - High-Quality Alternatives for Carbon-Ceramic Brake Systems

Replacement brake discs for ceramic systems are designed to restore braking performance on vehicles originally equipped with carbon-ceramic brake discs. These replacement options provide a practical solution when ceramic discs become worn, damaged, or prohibitively expensive to replace, while maintaining strong braking performance, predictable pedal feel, and system compatibility.

Available from Design911, replacement solutions for ceramic discs are commonly chosen by owners seeking a cost-effective, serviceable alternative that allows continued safe road or performance use without the extreme replacement costs associated with carbon-ceramic components.

What Do Replacement Discs for Ceramic Systems Do?

Replacement discs for ceramic systems work with compatible pads and calipers to safely manage braking loads.

Core Functions:

  • Restore braking performance when ceramic discs are worn or damaged.
  • Provide a stable friction surface for compatible brake pads.
  • Maintain predictable braking response and pedal feel.
  • Support safe road and performance driving conditions.
  • Allow continued use of vehicles originally equipped with ceramic brakes.

These discs offer a practical braking solution where original ceramic components are no longer viable.

Why Do Ceramic Brake Discs Wear or Fail?

Although ceramic discs are highly durable, they are not immune to damage or wear.

Common Causes of Ceramic Disc Failure Include:

  • Thermal shock from improper bedding-in or rapid temperature changes.
  • Impact damage from road debris or incorrect handling.
  • Surface degradation from incorrect pad compounds.
  • Cracking or chipping due to extreme load cycles.
  • High replacement cost, making repair impractical.

When ceramic discs fail, braking performance and safety can be compromised, requiring a suitable replacement solution.

Why Replace Ceramic Discs with Alternative Replacement Options?

Replacing worn or damaged ceramic discs with compatible replacement options provides a cost-effective and serviceable braking solution.

Key Benefits:

  • Significantly lower replacement cost compared with ceramic discs.
  • Reliable braking performance for road and fast-road use.
  • Easier servicing and pad replacement.
  • Consistent pedal feel and braking response.
  • Practical solution for long-term ownership and maintenance.

Replacement discs allow drivers to retain confidence in their braking system without the expense of full ceramic disc replacement.

Highlights

  • Replacement brake discs for vehicles originally fitted with ceramic systems.
  • Cost-effective alternative to carbon-ceramic disc replacement.
  • Predictable braking performance and pedal feel.
  • Suitable for road and performance driving.
  • Ideal for long-term maintenance and ownership.
