Hi I just got in. I had an emergency with my 5 year old daughter unfortunately. This is in the Med Heavy truck category instead of construction and road equipment. I help in both categories but I will e mail the site to correct this. What is your serial number of this machine?

Thanks for the info. This machine has an accumulator in the park brake circuit. Check the accumulator for signs of oil on the nitrogen gas side which would indicate a faulty accumulator. There could also be a low nitrogen charge on the accumulator as well. Copy and paste this link in your browser for the online parts book to help you identify the components. Check for leaks or for worn brake pads or seized caliper at the park brake caliper on the driveline at the transmission. Let me know the results and if you need more help.
