When I am braking from around 50 mph to a stop, when i get near 25 mph i can hear a humming noise and then the noise peaks (gets loudest) around 15 mph then dies back down. It sounds like a humming/grinding noise, like there is surface rust on the rotors but in this cars there is none. The dealer says its the tires, but i don't believe them...

i've never had a problem like that in either of my IS'. when u have enough open space, you can try braking really hard to get rid of the top layer on the brake pads... that might help, but might not. do u feel the steering wheel wobble at all when braking??

I had that problem with my 2001 IS300, but with the 2003, it's all normal. It feels like its happening but its not (prob cuz im so used to hearing it in the 2K1)

I think im hearing the same noise, i think it might be a problem with the abs prematurely kicking in. Have you found a solution to your problem? if so let me know

Mine does that too. I think it's from the tires not the brakes.
