I would be kind of surprised if there were electronic format (PDFs or HTML) manuals for this truck, and kind of think it is not so much an MCFA product as it was most likely made before the "joint venture" that created MCFA, (but I could be wrong) and is more of a Cat lift truck product. I was kind of "married" to a v925 back in the early days of the V925s. I do think that your local Cat forklift dealer can get up with tech support at MCFA to get the information, schematics and manuals you need, but it may take a few weeks to get the printed manual in your hands and a few days to get any sort of information. my memory of this truck's brakes are that it is air over hydraulics over a wet "clutch pack" type brake system that is integrated into the 'final gear reduction drive' at the wheels, and nothing is small on this unit.
what are the symptoms you are dealing with?
