246 Brakes Don't Hold When Engine Running

246 Cat brakes hold fine when engine is off, but creeps when engine is running. This is puzzling me. What would pressurize the release circuit when my hand is off the joystick? Is there something wrong with the pilot circuit or joystick (besides leaking)?
What to look for?

hi, a serial number will help is this machine a straight 246 or b,c
the park brake does not apply unless called for or there is a fault
creeping can be caused by incorrect adjustment of the neutral position or a problem with the pilot system

Thanks for the reply, Mark.
It's a straight 246, 2001 model 246A5SZ05XXX. I haven't been able to find any manuals for models that old.
