Weird humming noise and vibration coming from brake pedal, even in park

Asked by Aug 26, 2015 at 09:12 PM about the 2004 Chevrolet Avalanche 1500 4WD

Question type: Maintenance & Repair

My 2004 Z71 Avalanche is making a weird humming noise that's been getting progressively louder.  I feel a lot of vibration in the brake and gas while in park, and the sound revs with the engine.  When I'm in park and press the brake it gets louder and the brake pad starts vibrating. Not sure what to do being I'm on vacation, about 200 miles away from home. Never had a problem before and always kept my truck tuned up and in good condition. Any thoughts?

Need to get it checked out for safety reasons, but it sounds like something to do with the anti-lock system, I am no expert on ABS but do know a lot about breaks.

The problem is possibly caused by the electronic brake booster pump. Have it checked.
