Disc brakes
Does anybody know why disc brakes seem to wear out so quickly these days?
Scored discs seems to be really common now and the garage always want's to change them.
Sometimes this can happen in as little as 20,000 miles.

Not sure what it is (could be copper) in the pads.
But it is down to the pad compounds used and the fact that modern systems are so much better at stopping cars than they used to be (and the cars are heavier).
Better braking = more friction = more wear I guess. Pad compunds may have changed, but disks are still made of steel.

I think garages regard pads/disks as an easy way of extracting money from unsuspecting punters.
As en e.g., at its 25k service I was told my cars pads only had 6k left in them and needed changing. I responded that 6k represented 20% of their service life according to them, so I would not change them, and I doubted that was all that was left.
Surprise surprise at the next service (37.5k) they still had life left in them.
