I have a brand new 2008 Hummer H2. When I apply the brakes, I'm hear a brake squeal. I thought at first that this was coming from one of the wheels. The dealership that I purchased the truck from said it should go away with a little driving. After driving 2000 miles, the noise is still there. I have now found that the noise is not coming from any of the wheels, but rather from under the hood.
You can sit in Park, and apply the brake pedal, and recreate this brake squeal, without moving the vehicle. If you apply the brake pedal hard and fast it will not make the noise. If you apply the brake pedal slowly (like in city traffic), it will make the squeal. The noise is almost the same as a regular brake squeal caused from a brake pad.
Do you have any idea what this may be? I know that the new 2008 Hummers no longer use a vacuum system for the brakes anymore.
have the same problem?
