    Default JD electric parking brake problem...Help Please

    I have a JD 644J loader with 2240 hrs. Stopped for a short break yesterday and when I was ready to back to work the electric parking brake would not release. Fuses are good, fluids are good and no codes show on monitor.
    Anyone else had this problem?

    Welcome to TBN, nice to have another member from NM, I am in Ruidoso.

    Did you check the switch and wiring with a meter to determine if it is working correctly? Dont know but does it require power for disengagement of the brake and is normally locked when power is off?
