Check those brake lines. I was sitting in my truck last week in a school parking lot waiting for my GF to summon me to drive up and pick up some bookshelves to take to another school. I put my foot on the brake and it went to the floor. I had just replaced the brake booster hose the day before and I thought maybe it had come loose so I popped the hood and it looked fine. I looked under the truck and saw a puddle of brake fluid under the diff. Turns out one of the hard brake lines on the diff had rusted through and let go. Luckily I was in a parking lot. I had just been on the highway. I loaded up the shelves and limped it to a gas station and waited for my brother to come and get us and the shelves. I went back later that evening when traffic was low and drove the few miles home along city streets using the weak front brakes and the engine and transmission to do most of my braking. I spend the weekend pulling brake lines at the junkyard and installing them. The truck spend one year at the coast and it really did a number on the fittings. I had to replace the front lines because I couldnt get the fittings off the brake hoses. I just cut the lines and installed non rusted ones from the junkyard.
