how can i stop this noise, pads are not worn, had them out and put back in with copper slip on anti rattle plates and still squeak and squeal, pads look ok,only about third worn, any suggests please, cheers woody

Might be time for new discs.

 

Try running over them with some coarse wet n dry first, see if theyve picked up some squeaky stuff.

Had exactly the same thing on my Skyline (which runs same calipers) tried two different pairs of pads and made sure copper grease etc....Got a friend to skim and take a thou off and cured the problem.
