All sorted.
My brakes have four pads per side (L+R) and they came out real easy,
Pads looked ok and I proceeded to remove the top clogged layer with a file (mrs cbr's home made christmas cake also works) leaving a clean surface on each pad. (Uneven wear on the left side so need to overhaul at some point).
A little copper slip on the back and back in.
Brake cleaner on the disks themselves followed by a light rub with low grade wet and dry.
30 minutes later - as good as new, just as well as I couldnt wait to get out in this loverly weather!
Will do the 'back' later! - thanks to all for help. Happy new year.
