Hmm. Have you noticed any difference with brake dust? The US Lexus IS brakes are also supposed to produce less dust, but I didn't know that any of our dealers imported them.
Never took notice really. I try and wash the car every 2 or so weeks so it doesn't get that bad.
Give the guys at Parramatta a call. I felt that it was unacceptable that the brakes would squeal so loudly when they were quite new.
