So caliber of, and start rubbing with rough sandpaper. The disc have a slight blueish/brownish tint which dissapperar after a little rubbing with grit150 sandpaper.
Ideally disc should be machined, but time is short, havent got the hardware for it and really didn't want to disturb the bearings.
After a while (10 minutes each side of disc) disc had got the right slightly rough surface, and all the miscoloration had gone - clear silver!
Next find pads - mintex at the left, Countys finest at the right (500 miles wear on them)
I fitted the anti squeel shims, and slammed the entire bit together.
Job done.
Daniel R. (aka SpitmkIIICPH) came by and dropped off a much needed lift. It is more rusty than rysty, but will hopefyllu clean up nice and work. A lift is defo needed. I can't get under the car anymore. I say it's because car has been lowered - some says it's because I am getting old and fat!
Anyway - here is the solution. Just needs a lot of care and grease/paint/slight repair
