Gents, an update, the squealing of my new pads (mintex 1144) has reduced to almost nothing, I' suspect that the squealing is due to pad contact with clean discs (when new pads are installed the discs should be cleaned of all old pad material), material from the new pads is then transferred to the discs during use, this appears to reduce the squealing, which was really only occurring When braking from very low speeds.
