Your brake caliper has one or two stone chips/paint chips. Then give him some love and get our Brembo brake caliper touch-up pen.
We were able to read the color using a color measuring device and then let it mix.
 
We are satisfied with the result, see for yourself!
 
Our preparatory work was as follows:
 
- Brake cleaner
- Silicone remover
- Apply touch-up paint
