Hi Park brake not disengaging while in reverse gear and sometimes in forward. When switching off the machine and then back on it would work a few times and then park brake would not disengage again. I have looked in the manuals I can't find any information regarding this problem. I would really appreciate if somebody can help me regarding this issue. Thank You

    Had a similar experience on a Deere 250D Haul truck. Check your brake lights make sure they are both working as should. On the Deere the chassis controller monitors brake light circuit and will make the transmission and park brake systems act funky if there is a bulb out or a wiring harness problem. Not sure if your Bell truck has same type chassis controller system but this an easy check.

    Also reverse lights and back-up alarm need to be checked.
