I'll add that if you can afford them, Porterfield R4-S brake pads are about the best I've ever used, period. Fantastic feel from the very first stop. Be careful and do an extended break-in (bed-in) period before, uh, "abusing" them though. Buy direct from the mfr at
www.porterfield-brakes.com . Figure about $225 for a compete set, front & rear, with shipping. Available for most newer MB's - 123, 124, 129, 2xx, etc...
