Brake squeal is caused by many different things,but it has become more of a problem recently after asbetsos has been banned from use as a pad material,and longer service intervals have neccessitated harder pad materials.
Anti squeal pads(which stick onto the back of the brake pads and are available from all good motor factors) cure 90% of all brake squeal,but sometimes it is the pads themselves that cause the problem.Greasing the backs of the pads is not a long term fix,as the grease melts and gets washed off,so the problem returns.Copper slip grease is not really a suitable product to use anymore,but there are other products specifically designed for using on pads.Also,chamfering the leading and trailing edges off the pads seems to help,in some cases.
We have had problems at work with the front brakes on a Peugeot 406 coupe(Brembo calipers),and had to try 4 different sets of pads(all of different materials) until the sqealing noise stopped......
I'd rather push my Alfa than drive a BMW....
