As a minivan in front of me put their left turn signal on late, I had to hit my brakes quickly and when I did my brake pedal went to the floor and I was pumping air and had no brakes at all. I swirved around the van and luckily I was on an inclined road as I was able to slow the vehicle down into a lot and then pulled the emergency brake to get the truck stopped. My front and back brake line blew out and my mechanic said I was lucky that I wasn't killed. Now the truck is not usable and the after 52,000 miles I feel this is a situation of defective brake lines.
