I picked up a Pettibone RTL10 loader/forklift ex military. She runs perfect, excellent condition. But after running her for 20-30 minutes we completely lose the braking system. The brakes are full hydraulics, no air. She stops on a dime then nothing. I believe it uses the main hydraulic tank for the brakes. We only use this machine 1 or 2 times a week in a boatyard, same scenario everytime. Any feedback would be great.
There is an accumulator tank. I believe it takes nitrogen. Any idea of what PSI I should looking for?
