Yes the rear discs might have saved me from losing my car. Imagine doing 65-70 mph down the highway in the left lane. The car in front of you is a newer Maxima, and in front of that some other newer car, and in front of him a state trooper, all going the same speed, all about the same distances apart. Behnd me in the right lane is a line of cars going slightly slower (we had just passed them). All of a sudden I see the nose of the Maxima drop, and the brake lights on HARD. I jumped on mine as soon as I saw this. I looked back and realized the cars behind me were now next to me, with a concrete barrier to me left... Needless to say I locked the brakes up hard, but with some pumping got the car stopped... Left a good 150+ foot set of tire marks though.
Turns out something had fallen from a truck (appeared to be a metal book shelf) and the cop didnt see it till last second. He slammed the brakes causing all of us to.
My friend was in shock and actually asked me how I saw them hit the brakes, and how I stopped the car. I had visions of me losing it, but I really feel like had I had the originally brakes... it would have been an accident.
