maybe coz SBS (and I might add EBC)
wanna flog their new 'Ceramic' range of pads
...for use on road or track goes the blurb
or maybe coz... and I heard this a long time a go....
sintered pads can 'weld' themselves to STAINLESS STEEL
rotors if used in racing or extreme applications
(something to do with the copper or other metals
in the pad mixture)
doesn't happen with steel cast iron or grey (nodular) iron rotors
..apparently!
still
I would like to find out
cheers
