2006 Lexus ES330 Base 6 Cyl 3.3L
grinding from brakes, intermittent, pads and roters look good, Minamum ware on pads Seems to be from front
Removed pads and checked rotors both look good. 41000 miles of easy driving.
Check the wheel bearings and hub bearing assemblies - sometimes the grinding may occur with new brakes and worn / faulty / loose hub or wheel bearings - causing a slight sideways loading of the wheel and brake rotor when under braking conditions.
