hi,appreciating your opinions,i was driving my rx330 in hilly areas,i noticed clear coarse vibrations in the steering wheel while braking specialy down hill,in high speed,had my 5000 miles service done one monthe ago and they did rotate the wheels but i just noticed the vibration.thanks

 

maybe you have bad brake rotors due to improper wheels installation.

 

you definately have bad rotors. there is a tsb out for that problem. they will change rotors, pads etc. your dealer is aware of the problem.
good luck

 

Anyone have the actual TSB to print out? I heard about this but my brakes have no problems at all so I'm not sure if the dealer would be willing to change my brakes when I aleady have 25K miles on the car.

 

this is a rotor problem and the rotors are covered for 4 yr/ 50000 miles. so you got nothing to worry about. also remember this is not a recall so it might never affect your vehicle. they basically change the warped rotors and other brake parts which had actually led to its failure, otherwise new rotors will mess up again.
