This morning I noticed the brake pedal traveling down further than normal and little to no stopping power. Once arriving at work I tried to pump the brake pedal and it kept going to the floor. Upon looking under the truck I discovered a puddle of brake fluid. After further inspection I found one of brake lines had rusted through and blown out in front of the abs module. The general condition of all the brake lines in this area is very rusty. I will likely have to replace all the brake lines due to this.
