Disco II Brake squeal - help!

Can anyone make any suggestions to stop the brake squeal on our Disco?

My garage has replaced disc, pads and put on a new caliper (as the old one was sticking) but when we drive through a right hand bend the offside front wheel starts to squeal. This can be stopped by a quick tug of the sterring wheel to the left or applying the footbrake - neither of which are ideal as we would rather it didn't squeal at all!

Any ideas welcome!
