HI, First of, I am not technically aware on this subject, so please forgive any rubbish I may write! I am having problems with brake "squeal". This happens when the brakes are warm and gets worse when they get hotter, under medium to hard braking. 1. Squeal was rear left ONLY. So I had a garage de-glaze the pads and re-grease both rears. NO fix. 2. New rear pads fitted. Have only done about 80 miles and I know I have to run in gently for a few hundred, but now when brakes warm up I still get squeal from what sounds like both rears! I find it hard to believe this will go away on it's own. What can I try? It is def. the rear, as I have had front's checked. Disks and Pads good all round. Should I have anti-squeal shims on the rear? (this is something I have read about, don't know if I have or not - garage did not mention and I forgot to ask).
