| The roads were snowy and parts of it icy, but it wasn't snowing. from a far distance i started to slowly brake so i won't skid. when i applied a bit more pressure to brake the car more, the pedal hit against my foot and wouldn't go down when i tried to force it. i think the abs came on but it did not slow my car down at all. the car was still going at the speed i slowed it in earlier but made no change. there was a line of cars ahead of me in front of an intersection, so i panicked and put the car in park and turned off the engine. the car finally stopped about 4 feet away from the car in front of mine. | |||

| I bought a brand new impala, year 2008. after approximately 10k miles i experienced a vibration in the rear when braking. when i brought the car to radley chevrolet in fredericksburg, they told me that the rotors were warped and it was my fault and not covered by warranty. they said that the lug nut torque was not correct and uneven. i never touched the lug nuts or rotated the tires as the torque issue was rear only and tread wear proved there had been no rotation. i went to chevrolet customer service who stated the radley service manager was such a great guy and he believed the service manager. when i explained that the tread wear proved the tires were not rotated he then told me that not rotating the tires was a maintenance violation also. i asked him that now you are claiming the uneven torque was due to me not rotating the tires. i am frustrated as i am right and never touched those tires or nuts. i am not even sure where the wrench is. *tr | |||
