Brakes

When new brake discs and pads are mounted.

How must be done the brake-in to reach the best results?

Brake pads and rotors each have their own break in requirements. It is recommended that new rotors be burnished with old pads and new pads bedded in to old rotors, but this is not a requirement.

When pads are bedded in two things are accomplished: 1) the binding resins are burned out of the outer region of the pad, reducing further "outgassing"; 2) a uniform layer of brake pad material is deposited on the rotors.

When new rotors are burnished you also want to put a uniform layer of pad material on the new rotor, as well as heating the rotors up to operating temperature and letting them cool back down.

In both cases, the procedure is to do a series of progressively harder stops.

The following article explains it all in more detail:

Many thanks for your information KevinC, I have read the whole article and has been very interesting for me. It cleared some technical points that I were not complete clare for me. Your are :welcome:
