Brakes were making a noise for a 2nd time; already replaced once when i told abc nissan phoenix, az (where purchased) that at speed less then 25 mph my brakes were making a noise. the other day went to brake at 14 mph in very heavy traffic on the freeway during rush hour and brakes locked up and had to use the emergency brake to avoid a collision (mind you i was one car length behind the car in front of me). i am afraid to drive my nissan altima now!! this is ridiculous. *tr
