I have a 2001 corolla with 36,000 miles. It recently had a 30,000 mile service done. The front and back break pads have been replaced with new ones. I have noticed that after the service, whenever i start the engine in the morning, i hear a strange noise/vibration from the front portion of the car. This noise comes, only when the brake pedal is pushed. The noise comes for around 2 to 3 minutes. This happens only when the car is started for the first time in the morning. Any pointers to whatz happening will be appreciated. Thanks Sanjay
