thanks for this. I had the back done also. I never had this sqeek or shudder until the brakes were messed with. Yea it does sound like the dust sheild kind of noise so will check the back but really want to get under the front and check them also. I guess the weight in the car would also cause this noise to get louder as they could be rubbing more.
How much would it cost for a garage to remove and clean the caliper pistons and also the slide pins as i am not very mechanical lol.
Like you this noise and the judder are driving me nuts, they car is quality except for this hassle which spoils the whole lexus driving.
