Can anyone tell me why material the oe discs are made of, the reason is I have some new pads but they only work on stainless steel discs, as the Japanese stainless steel is low grade it is magnetic so that is not an easy way to tell.
Stainless steel comes in a plethora of grades, & some are magnetic.
Unless you've got a 70's jota or guzzi it's most likely going to be stainless now
The problem with socialism is that sooner or later you run out of other people's money!
The pads I have are ferodo sintergrip road HH rated, I know these pads are for stainless discs only, and some jap bikes do use cast iron discs as standard.
