Mustang 2022 Parking break locking up HELP PLEASE

[diggeringo]

Hi guys , I have dramas with the parking break. It started about 3 month ago, that the break will lock up while working. It is getting worse now ,If I start in the morning I could work 30min than it starts to lock up again, when I just wait for 20-30 min the park break switch turns to green again and I am able to work for anothe 20 min or so. Once it has locked up it does not show the red light in the instrument panel . It lights up after 20-30min as explained before. I can use the park break and it works fine. I also changed the solenide Valve and no change . I also changed already the park break switch in the Instrument panel . Is there anything I could check ? Does the 2022 has break timer and what does it look like . I would appreciate your Help Thanks heaps Guys!!!

You have replaced all the main parts, the only thing left is the relay?
If it's like bobcat ones, there will be three wires, ground, pull and hold. If there is any power interruptions on the hold coil the brake will come on.
A safety sqitch like seat or seat bar, but for that i'd suspect a light would come on or turn off to notify you.

Not sure if your model has it or not but our 2044 and 2054 have a timer behind the dash panel between the switches that act similarly when acting up. They can be bypassed. Don't remember the 2 wires I will look back and see if I can find it. I looked back and it's the 2 orange wires on our machines. Don't cut the wires just jumper the wires
