They must be well on their way now then.
Nope ~ I'm not that heavy on brakes! And it is a rear brake when all said and done.

Can't see why a snail needs brakes at all.:)
To be sensible for a moment, pads and discs changed on my diesel Focus at about 65k.
Drums at the back which I don't think have been touched.

>>>They must be well on their way now then after 37,000 miles
Says the man who has a Volvo that has been to the sun and back and is on its first set of discs and second set of pads?
|
>>They're the original pads. (The car has only done 37,000 miles.) <<
It's not the wrong parts / poor fitting then.
I'd still guess at a sticking / seized caliper. Take it off and clean it up, make sure it operates smoothly and applies both pads evenly.
You can probably only see one side of the disc - the inside may be much worse.
The mileage isn't really relevant.

There is a shield on the inside, but with the aid of a torch and a mirror I can just see the disc in two places.

If the surface corrosion has progressed to pitting corrosion then a fair bit of metal will have to be removed to eradicate the rust. And, as already suggested above, if the pad and discs are not running truely parallel then it certainly appears that the outer circumference is not being heavily contacted.

The transition from the clean part of the disc to the corroded part isn't gradual, it's absolutely abrupt. I can only assume that the corroded part is more abrasive than the clean part and hence it wears the pad so quick that there is never any real pressure between the pad and the disc in that area and the corrosion is never removed by the pad.

I wonder whether the components are of different sizes compared to the other side, or whether the pad on that side was faulty and/or has broken away. I realise these are original fittings.

That doesn't fit well with the other discs being different, and that there's an abrupt change in surface condition.

It's not unusual for manufacturing or assembly irregularities to result in slight differences between the positions of pad surfaces in relation to the disc, or for the pad friction material to be slightly differently placed on the pad backplate. Sometimes differences are present in the calipers too. My impression is that some makes of pads are better and more precisely finished than others. Perhaps this is an extreme example. 8mm does sound a lot though.
