if it is making a squeaking sound, it could be a number of things. either the belt itself, or any of the pulleys the belt is conected to. if the belt looks ok, take it loose and wiggle the pulleys that are connected to it. they shouldn't have any play in them, but if you find one that it even just a little loose, that is probably where the sound is coming from
One of three things. I would start with removing the belt and checking the idler and tensioner pulleys to see if they are running smoth. The third item would be the ac compresor brg.
go with standard pads.they wear a little faster than ceramics.but they dont wear down brake rotors.ceramics pads are hard and they cause brakes to squeak.also your car is under warranty with lexus dealership.i would use what they said. because you have future brake problem. they will void out warranty for not using their brakes.
If this sounds like a tin can rattle it is likely a loose heat shield on top of the catalytic converter. They come loose after time and corrosion take their toll.
never had that problem with my GS400 but on my 95 maxima, i used to have that same high pitch squealing noise... i used some belt dressing that i got from R & S Strauss for a few dollars and sprayed it on my belts and pulleys that ran around the alternator, compressor, etc. and never heard the noise again. hope your problem is as simple and cheap to fix as mine was
