Hey Everyone,

Been awhile since I've been on here, I've got a 00 Lexus GS300. A couple of months back I swapped my front rotors and afterwards when I would come to a complete stop the brake pedal would "buzz" and vibrate just as I was coming to a complete stop. Sometimes it will "buzz" multiple times, other times like the video it will just buzz once. I've searched the forums and the two common suggestions are:

1) Replace the brake master cylinder assembly

2) Replace the wheel speed sensors

I don't think it's the wheel speed sensors because those also light up the dash board with warning lights, and I don't have any of those. Brake fluid level is good and doesn't seem to be leaking.

Thoughts?

just the rotors?

When it happened to me it was one of the wheel speed sensors. Have you tried checking for any codes?

For what it's worth the same just started happening to me after I replaced my driver side spindle. My BMC is a newer '03 model and it never misbehaved until my recent front end work (I'd diddled with my speed sensor too).
So, I really doubt it's the BMC itself, rather just the speed sensor (I hear they're really sensitive).

Before I spend the bucks on a new speed sensor, I'm gonna give the brakes a good bleed since I didn't change the pads and pushed the brake cylinder piston back in the process. I don't think it's an air-in-the-system issue, but I'm hoping so

Odd, I would've thought a speed sensor would light up the dash like a Christmas tree? I have no warning lights that I typically read about.

Mine was intermittent. It would come on for a few hours then go off for a week and it only made the buzzing noise stopping from 5-10 down; otherwise you'd never know there was a problem.

I have the EXACT same issue, I replaced my passenger side abs speed sensor cause it snapped, both ball joints and struts.

The car right has the VSC light and check engine lights on since he work was done. I got it check at the dealership they recommend changing the oxygen sensor.

I has no lights on my dash before the work was done, my brakes worked fine as well with out creating this noise.

I think all this has something to do with the ABS sensor.

Any suggestions? Were you able to resole this issue?

I'm having this exact issue. My 01 BMC and a newer JDM BMC both produce this issue. Car doesn't throw any codes and there are no lights on the dash. Brakes have also been bled. I'm puzzled.

I'm not mechanically inclined but after reading this thread:

I'm gonna take a peek at my abs rings for *****s and giggles when I get back to my GS. 🤷🏾*♂️
