The shock mounting, driveshaft gaiter & bushes don't look too good either, looks like they're all caked in rust and other crap. Wheelbearings are probably knackered too looking at the state of everything else.
Solid brake discs are nearly an inch thick. (Ventilated ones are thicker) They wear down maybe 1/32 of an inch every hundred thousand miles. (I am completely making up these numbers, but they should help you visualize).
Now figure out how stupid or bad a driver you have to be to wear them down to almost nothing?
Surely in this time, you would have had pads replaced a number of times? or else with that kind of wear you would literally have nothing to brake with... so surely somewhere there must be some ass-brained mechanic that didn't notice?
.. I had totally brake failure once, discovered it at about 60mph on the dual carriageway from Camborne edit Redruth. Popped master cylinder.
edit 2: I am so tired. English is poor what isn't it.
