While I was cleaning my front calipers, I noticed that the shiny SS spring thingies

have changed colour since I last looked at them properly - they're now a metallic beige, dark straw, sort of colour - a little darker than my link pipes. The colour is uniform on the insides, blotchy on the outsides. This suggests to me that the brakes have got quite hot at some time. The pistons & pads were moving freely before I cleaned the brakes, and I've never been aware of any drag. After I replaced the levers last year, I almost obsessively checked the brakes for symptoms of overheating, sticking, dragging for the first few rides, but all was well.

Anyone else had this? Am I being paranoid?

Just natural tarnishing and a smattering of brake dust, nothing to be concerned about.

They're stainless - shouldn't tarnish like that?

If you translate stainless steel into any other european language it becomes rustless steel. I wonder why?

I take your points, Bobbi & Sam, but I'm sure they weren't like that last time I cleaned them thoroughly, last year sometime

They've had a year to get like that then.

Check out a stainless exhaust system that goes through the extreme heat cycles that your brakes do and you'll see that will be just as bad, if not worse, for tarnishing.

A quick and easy way to find out if they're rubbing is to stop without using the brake in question and quickly pat the disk with a naked hand. Anything involving pain and blisters points to a sticky brake.

Probably not a very high grade of stainless steel. I can make them bright and shiny again, but it's a bit of a trek down here. You could post them to me I suppose

If you.want.them shiny again just clean them on when you remove the pads .
The Sv crowed use HG wheel cleaner on the stainless exhaust.

HG (and other places) sell some great stainless cleaner called Optiglanz - expensive but it is the bollox of the dog

Great on Falco exhausts (not so great on your hands when you are not too careful with it ........)

Not too bothered about the appearance; might get round to it if I sell the bike
