Thanks for your advice!
Today I took the time to make the pad bedding ref. to
Zeckhausen Racing .
After the bedding I realized that the alignment between rotor and caliper has not been 100%.
I adjusted the left and right caliper approx. 0.3mm or 0,011".
I repeated the bedding procedure and the rotors showed an equal contact/ square.
I also changed the balance between front and rear brake. Too much front brake pressure.
More I will let you know after the next test.
