You are missing the most important part of the model #. There are 2 letters after the #. They are most likely "MB" or "MC". The MB means that it has conventional brakes and the MC means that it has disc brakes. The problem with the MB brakes are they are extremely difficult to bleed. They need to be bled from the wheel cylinder up to the master cylinder. The problem with the disc brakes are that they bleed down if the truck sits for 2 or 3 days.
