Loader New Holland C232 Park brake and hydraulic problem

[rhukill]

I ruptured a 3/4 hydraulic hose to the right side final drive, lost all hydraulic fluid and tracks and controls stopped immediately. I replaced the hose,fluid and filter. Now the park brake won稚 release until I push the throttle to half throttle. When the park brake light goes out, the left track and boom function normal but the right track and bucket won稚 function. When the throttle is pulled back below half throttle the park brake light comes on and all hydraulic functions stop working. I checked fuses, wiring, plugs, solenoids and fluids at the cylinders and valves all are good. Perplexed!

Sounds like an internal leak is preventing hydraulic pressure from building. There are probably test ports for installing a test gauge to map system pressure.

Time to buy a service manual.

Thanks for the reply, I found a mobile heavy equipment mechanic that is supposed to look at it next week.
