Buzzing Sound

Hello everyone,
I recently started hearing a buzzing sound when I press on the brake pedal. Is it my MC craping out on me or ? Any help is greatly appreciate.


Thank you

Sorry about that, the sound seems to be coming from around the dashboard area. It only makes that sound when I'm driving not when I'm at a complete stop.

Thanks

Funny, I'm also getting an intermittant buzz from my dash area. Just started a short while ago. Has me baffled.

Strange.

Maybe a relay? I had a power window relay that conked out on me recently. It started buzzing shortly before it went out.

There is a little play side to side but the pedal is all the way up so I really can't lift it up more. The buzzing sound is more present at higher speeds (>35) than at lower speeds (<35)

Pull the tach and remove the buzzer(relay?) for the door buzzer. Mine actually started buzzing while the car was parked in the garage. See if this solves your issue.

Depending on the buzz, could it be the fuel pump?

Sorry for the delay in responding. I replaced the brake pads, and rebuilt the driver side caliper and the sound went away.
