Textar made the pads I installed on my 280E and they didn't squeal and did a great job stopping the car but the amount of dust was horrible. I am pretty sure I have ceramic pads on my 300E which has no squealing or dust but the pedal is firmer than my 300TE which doesn't have ceramic pads and produces a lot of dust. Akebono is one brand that lots of folks here recommend if you go ceramic.
