Pads...
 

I'm gonna sound so dumb asking this, but here goes...
Do brake pads go "off" like tyres can do?
I'm not talking about while they're being used - I mean if I was to buy in bulk while I'm feeling flush, would they be ok to keep in thier packaging in the garage for a period of time?

Yeah, no probs.

Yep. Felix is right. They've got a pretty good shelf life. Just make sure the packaging is air tight. If they were to get damp, then they'd start to "go off"

Yeah, like rusty of their sintered like HH.
