Hi guys, no here, so bear with me. We have a 2050, that has been having intermittent problems with the parking brake. The machine will run fine all day, while using the brake and control locks all day, then it will just pick the worst moment not to unlock. The boom still moves up and down, but on both sides, the wheels are locked up. Both switches have been replaced, I don't remember if the timer was replaced yet, fuses are good, and the small black box with the 35amp fuse in the engine compartment was also replaced for another issue. Through my searching, I have heard the brake solenoids could be an issue. I believe they are in the case under the seat, correct? Like I said, it just picks and chooses when it wants to do it. It has been shut off with no problems, and then won't move the next day. It has stopped during the middle of a workday, and has unlocked after sitting for about 15mins. Has anyone had these issues before, and if so, what have you found to be the problems? Thanks.
