Do sintered Pads go "Off" ?

So then, in the name of science...
My new pads should be here this week.
If I change just one set and they rust just as quick, then that will prove that age makes no difference and therefore they do not deteriorate.
However, if the disc with new pads on stays cleaner, that should prove that they do deteriorate.
I've said with age, but that is not strictly true. Exposure to the elements may be more of an accurate description.

Variables...
Which side?
Should I clean the surface of the disc before fitment?
Should I try to clean the old pads?

The material is uniform through the thickness. In this case it's the discs not the pads that are rusting I think. Not all discs are made of exactly the same type of steel. Some types of steel rust more easily than other. The selection of metal was probably made for reasons of heat dissipation, resistance to warping, friction, and cost.

Things rust fastest in warm, wet conditions with a catalyst like salt. Guess what conditions those GSXR/TL discs have been in?

That's the reason why I asked what discs they were.

Ebc discs are notorious for turning orange if you so much as sneeze at them. I can gaurantee they are orange now! They aren't wearing thin either....not even worn in yet

So, Suzuki iron it is then Davie

Blimey, neither of my SV's had discs go that rusty and that included being left outside all winter.

But why now?
Why not last winter or the winter before???
Same run to work, same conditions, stored the same...

Might be more salt on the roads maybe? Acid rain erosion? More humidity in the air?

[DavieSV]

It's not just happened today, been like it for last two or three months.
It was just highlighted today after being stood all over Christmas and I had to drag it up the drive to free it this morning.

Ummmmm dunnoooo

Can't offer any other possibility in that case!

All Japanese OE discs are made of materials that do not readily corrode, this is for appearances sake mostly, many older Italian bikes had iron discs that corroded if you parked near a damp sponge, the material of the disc is very important in this question, what are your discs made of?
