Dave, well, I got my new rst and the brakes were fooked on it, I put my pagid discs off my old one onto it which stopped the judder I was getting and kept the standard pads in place as they have a fair bit of meat left on them. I think u will find the probs of squealing is the pads I kept taking mine out weekly to re copper grease them, it worked for a short time but this became a pain after a while so just took them out, they are like new tho and just put em on the bench for spares. Only kept the standard pads in for now as I am gunna upgrade to ST170 setup
