Check this thread. It has video (beginning) so you can compare the noises.
Replacing the master cylinder is so often suggested, in my case it had something to do with the ABS sensors (actually rust in the wheel hub that damaged the tonering= ABS sensor 'reads speed from axle').

i have yet to see or hear someone besides u report a 2001+ with these symptons.ESPECIALLY since they re-engineered the brake booster in the 2001+ units. last TSB on this i saw was for the 2000. soooo yeah i think i can safely saw it was the 2001+ units (although since im NOT 100% on this, i will admit i could be wrong. i just dont recall anyone but you saying a 2001 + had this issue....preferably the brake pedal vibrating as some people could mistake the servo buzzing to be this) no EN_VY not referring to you...since u did just say something bout this i didn't want u to think i was talking bout u

Okay so now you have heard from 2 of us...yep that's right, I cranked the car and it started making a loud buzzing noise, sounds like a cell phone vibrating behind the radio display...and when I press the brakes sometimes it happens too but not all the time. And also just in case this helps...I think this car has electrical problems because the radio display goes in and out sometimes, and the dash lights fade in and out sometimes. Any suggestions, don't have any money...

Buzzing noise in dash area GS300
Johndoe619 - did you ever find out anything about your buzzing noise...I need something that isn't very costly to fix this problem...hate to take it to a mechanic without some sort of idea of what I am getting into....see my post from yesterday.

So on my thanksgiving I had the joy of losing all braking power...I have a 2002 GS3. M abs/VSC and VSC off light along with brake light on...I got the loud continuos noise and I have no brake when trying to stop...lexus lied when they claim they fix this issue after 2001. Anyone have a master cylinder for sale?

Im having this problem now on my 2002 Gs300. It has 177,000 miles on it. When I start up the car I hear the buzzing sound for about 4 seconds and then it kind of makes a knock sound and stops. This also happened occasionally when I pull up at stop lights or in traffic. Brake pedal feels a little mushy but nothing serious. I have seen the ABS/VSC lights come on maybe 2 times since I bought the car 6 months ago. Each time I turned the car off and started it back up. Does this sound like I need to replace the entire Brake Master Cylinder? Kind of disappointing considering everything I read says the 01+ are more reliable.

Ive always suspected low nitrogen to be the case with most of the problems ppl face concerning the brake master cyl. but I didn't know the canister was available and can be changed.
Anybody successfully changed out theirs??

The way u could tell that it could be the accumulator is when you hear the pump motor priming about every 10-15 seconds. If you have a bad accumulator, this will also wear out your pump motor too since its priming constant..
