Not a fun feeling when you push the brake pedal and nothing is there. Truck box was loaded with construction tools and was pulling an empty trailer when this occurred, luckily i was on a lightly traveled road and was able to engine brake it by downshifting and no one was hurt or any damage done. Rear passenger line had been worn through by the tire and fluid was everywhere. truck has 6600 miles on it. Wondering if anyone else has had this happen. Thinking of putting zip ties on to pull them a little further away from the tires. I do have a 4" lift and 35-12.50 tires on it.
