I recently went to a Sears Auto care and was told that I absolutley had to have ceramic brakes on my es300. They also happen the most expensive type. Is she milking me b/c I own a lexus or giving me good advice? Also, she said that my rear rotors need replacing. My car has 134000 mi. and I have not noticed any brake noises. Is it likely that my rotors are damaged? Any help would be much appreciated. Andrew
