Both front hydraulic brake lines corroded on drivers side, with loss of braking, on chassis top rear of front wheel. It appears that there is a large wiring loom (1 1/2" O.D.) clipped on top of hydraulic lines, one to lf and rf wheels. Corrosion on both lines are at the contact of the loom and lines. Vibration may have caused the loom and lines to rub and allowed moisture to corrode the brake lines.

When coming to a stop the pedal went to floor and had no brakes. Luckily I was able to swerve and miss the vehicle in from of me. But had to run through the four way stop and was blessed to have no other vehicles in way. The brake fluid was leaking from under the driver side about where the seat is. Upon investigation, the lines are all corroded and rusting. Obviously it only takes one to leak but all need to be replaced. This is such a surprise because this truck sits in the garage most of the time and has very few miles on it.
