Constant Whine Coming From The Rear

[Barratt1982]

So i have this awful whine coming from the rear wheel area when doing 30mph + its like a high pitched scream, last week i had lexus change the rear discs and pads in the hope that would solve the issue (£310 actually wasnt too bad for lexus) and although the rear discs looked shot to shiv.. this hasnt solved the issue... anyone else out there with an issue similar, i have read a few posts about lodged stones or back plates catching but would have thought with a new disc and pad this would have been spotted.

Hopefully they changed the rear shoes as well as the pads?

If they have just changed the disc without cleaning the guard and by cleaning i mean by using a grinder or some sort of abrasive tool to remove the rust from the guard (the lip that is inserted into the disc) then the noise will still be present as the rust on this shield, which there will be, will still be creating the screeching you are hearing when the wheel is rotating as it rubs on the disc.

Was the noise explained to the dealer when it went in as they possibly just done the job with no road trial after as when up to temp the discs will expand a little so what might seem like a good initial job with no noise after doing the work could be masked by the fact that when driven for a period to get the discs to temp the noise appears again.
