Almost any mileage between 5k and 50k are possible, some drivers live on the brakes, others barely use the brakes making use of terrain lifting off early and engine braking, town use is heavier, motorway use should see almost no wear at all.

I would concur. Now I'm old I very rarely ever fit a set of pads but in my youth I seemed to always be changing them. Depends almost entirely on how and where you drive.

Agreed - I've had a 2 tonne SUV with only half worn brakes at 50,000 miles - being retired I never drive in a rush hour and even the motorway runs are off-peak - I do also tend to leave a larger gap and anticipate better than many. On the other hand, my son drives more agreesively than me, always in heavy traffic, so only gets 20,000 out of a set.

In an Edinburgh MOT context, I found brake pad and brake disk life seemed to be inversely related.

Since, being Yorkshire/Scottish, I drove to minimise fuel consumption, my brake pads lasted a LONG time (can only remember buying them once).

OTOH I had to replace the brake disks for "visible rust" at every MOT.

(Admittedly I usually only MOT'd every 2nd year).
