2007 Chevrolet Impala braking system grabs and shakes car excessively when using the brakes to control descent down mountain roadways. This has also occurred during commuting to and from work when the brakes are used quite often. The braking system was tested by a Chevrolet dealer, three days after the mountain driving problem. The rotors and pads were in excellent condition and no problem could be identified. A web search identifies other complaints of this same symptom. Although no damage was caused, the car was operating in a very unsafe manner. Even at 30 - 40 mph the car was shaking enough to degrade safe control.
Rear alignment not within specs from factory, caused rear tires to wear prematurely. Front disc brakes needed replacement 11,000 miles and rotors needed to be resurfaced. Chevy would not cover the repairs under warranty.
