Quote from article:
" If possible, new discs should be bedded with used pads of the same compound that will be used going forward."
The idea is that the pads will have already gone through the process of releasing bonding resins and other residuals from the first bedding in process, will have already established the taper due to caliper design to create a good relationship to the rotor surface and will be more effective in "seasoning" the new rotor.
Old proverb:
New pads, old rotors
Old pads, new rotors
