Temperature evolution** (sx) and friction profiles (COF vs. speed) during bedding.
** The time is only related to the brake application, it does not refer to the cooling.
Typical appearance of a correctly bedded set of disc/pads (sx) compared to a new one.
Blanking
Attention
Due to thermally induced mechanical stresses, cracks can develop despite
perfectly bedded brake discs and pads. A critical value for the magnitude of
these stresses is the minimum temperature of the brake discs at the beginning
of braking – especially at the end of a very long straight. Subject to circuit
layout, it is therefore necessary to partially blank the brake cooling air ducts.
