The left ones aren't wearing so evenly, but there's a bit of life left in them (the spring obscures part of the friction material so the outer pad isn't as bad as it looks).
But I reckon this is the cause of that noise.....
There's a noticably rougher patch on the left hand disc, and when you run your finger over it you can feel that it's raised slightly. I can only assume that this bit sat in contact with the pad which kept that bit of the disc wet for a couple of days, so it's gone proper rusty in that area which isn't rubbing off
. Does that sound like a realistic theory?
