I have gone the whole hog - put new discs and calipers on - the Greenstuff pads have only been on 9 months so kept them - On a trip to take the old caliper back for deposit I tried brakes a few times and smooth as silk - no judder at all - Said to bloke in Auto shop if I come in again for anything brake related refuse to serve me. I have not messed with brakes since early 80's and don't intend to again till 2080s.
