Gnasher, i am hearing you mate, but there's really nothing to look at to be honest?
The discs are totally normal to look at, with even disc rotational markings.
If you read the website i posted before it does say that if there were 'deposits' then you wouldn't be able to see them anyway, which i can't!
Believe me i've spent so much time handling discs over the years i'd spot an abnormality a mile off it was visual.
The fact that i've had different new sets of pads and discs and the same problem has reoccurred theoretically rules them out as a source of the problem, they're just a reaction to the issue.
I'm trying to eliminate things in my mind but as you can see from my earlier post i've tried the majority of things, apart from a new caliper or wheel.
I really don't believe it's the wheel, so that leaves the caliper, which i never really suspected before because it all seems to be functioning ok.
It's not even the type of problem to give to a bike shop because they'll just say get new discs and pads, and that habit is getting way too expensive!
***** THE LAST PHOTO SHOWS THE BRAKE PAD RETAINING PLATE MODIFICATION *****
2mm taken off the bottom edges (the very lowest lip part), and the top part completely flattened out with a hammer until it is a straight, flat piece of plate metal. (the arrow on the pad should be at the bottom pointing upwards, the same way as wheel rotation)
It's a much tighter fit when put back on, and holds the pads in a forward position only, so they can't rock back and forth.
NOTE: There is no bent over lip on the top left part of the plate in the photo, it is completely flat, the photo and grubbiness(crappy weather, sorry), makes it a little bit deceiving!
