TR6 brake squeal question

[Creigtrium@aol.com]

My TR6 front brakes squeal very badly.  What is the best way to fix this 
problem?  Do the brake pads that advertise that they are made of anti-squeal 
compound really work?  If so, is one brand or vendor's product better than 
another?

Or should I get new anti-squeal shims and coating and replace the old ones?
