For optimum performance, please follow the running-in phase described below:

1. Plug the cooler inlet to 3/4
2. Use ground (hard) inserts
3. Gradually heat the discs for the first 15 kilometers.
4. Use the vehicle normally without being violent on the brakes.
5. Finish with 5 or 6 violent brake applications.
6. If thermal paints are used (part number CP26491) only the green paint (430°C) should have whitened and the orange paint should barely begin (560°C).

In order to operate at the best efficiency and last as long as possible, the disc temperatures must be correct and balanced.
In general, all discs in a vehicle should operate at the same temperature.
The maximum disc temperature should be in accordance with the quality of the pads used.
Disc faces should not exceed the maximum recommended temperatures for each type of wafer.
