If the caliper isn't sticking, it's something to do with that shocking dice on the valve..

Is the caliper carrier on square?

Caliper is not square to hub or caliper is not central to disc.

better off with 170 calipers anyway as they give more clearance for the rim but as chaps have mentioned those carriers must be mounted on the piss or something

I wouldnt have thought so unless it is making the pad retract unevenly / or clamp unevenly....sounds like the braking system might need a good coat of looking at.

wear like that on the disc has nothing to do with hoses its the carrier bracket not being true so caliper is on the piss unless your piston is split in half

Looking at your pic I would guess that the rear of the disc is clean on the opposite to the front.
so the inner would be clean and the outer rusty.

for anyone interested i changed the caliper and carrier this morning, the brakes instantly seem sharper and i think the rust area has faded slightly, ill let them re-bed and hopefully job done

the old caliper i could swear the piston was at an angle...
