Thanks for the info about the pads. I found a Technical Service Bulletin from Lexus about the 99 through 2000 Lexus that the pad support plate, shims and brake pads need to be replaced and have been modified since 2001. So when the dealer tells you this is normal, no it is not. This is something that is covered under warranty and Lexus is responsible for fixing this. What I can't understand is why doesn't anyone at Lexus know about this Technical Service Bulletin put out by Lexus or do they just find it easier to just tell people this is just part of owning a Lexus. Do not let them get away with this.
