I dunno if neone else has experienced this but ne clues would probably be helpful. I have an A/T and whenever im driving and then hold the brakes down and come to a complete stop, after about 2 seconds of stopping, i let go of the brakes and after fully letting go a small vibration goes thru the underside of the car and the shifter vibrates a lil bit. the longer ive held onto the brakes, the longer the vibration is. ne clues?? thanks in advance

 

I have a similar problem, but mine occurs when I start the car when the engine is cold. There's a vibration/buzzing sound that pulsates through the brake pedal. There's a 5 second delay between them and it goes away about 5 minutes later, while I'm driving. I posted this prob awhile back and someone said it was the ABS cycling, but I don't have any check engine lights and the brakes seem to be working fine.

Not sure if it's the same prob your experiencing, but it's close. I took it to a shop, but like all gremlins, it didn't happen when I was there. I hope someone can chime in with the know.

 

thanx..its close, but mine happens at constant intervals after i let go of the brake pedal..rather weird..newayz bump to the top..got finalz so no time 2 take it to ma mechanic
