ime most common cause of sqeel is cheep pads with no shims on the back, you need a shim material to take out any osilation if the pads dont sit perfectly flat in the caliper, if they rock they ossilate, and do so at such a frequency as to squeel. The more they rock, the louder the squeel. Shims, preferably ferous, ime.

Agreed. Lack of any shim material doesn't help, and the OE pads have it riveted to the pad backing. TC pads don't.

It might be worth filing a chamfer on the leading and trailing edges. I had the same problem with mine but they have eventually quietened down. They still make themselves known every so often.

I wouldn't say fitting a performance brake pad is a solution to a comfort issue. Bear in mind that some of the harder EBC pads need some heat in them before they work well, so, in my opinion aren't great on a road car. Green stuff would be OK but if fitted without shims I doubt they will improve matters.

One thing I noted on my front brakes from 2001 Catera is that the piston surface given the years of bad brake jobs shows lot of uneven corrosion.  Just as one cleans the front hub to properly mate the new discs, I believe a light even filing of the piston fronts can be very helpful.  After all we are looking for most contact and consistent pressure across all surfaces when brakes are applied.

You people know lot more than me, just something I noticed recently while doing my brakes.

Regards.
