I have a 54 630 with a 503 and 15000 miles. It was a tanker fire truck and I have taken the tank out. The driveshaft has a pretty cool mechanical disc brake setup for the emergency brake but the disc is mounted to the main fire water pump. When I took the pump out I'm not sure how to mount the disc for the emergency brake. Has anyone done this. I don't want to leave the pump in for a number of reasons. One - the pump sticks up above the frame rails, so I would have to raise the bed floor. Two - I don't want to have to keep maintaining the pump. Three - It's heavy. I don't want any extra weight.
Thanks in advance for any ideas.
