I have a 2012 Cat 289C2 and the parking brake will not release. Sometimes it will release for a few minutes but then will lock the machine and it will not move. Not sure what the problem. Any help would be appreciated.
See the attachment in Post #4 of the linked thread. Find whatever Active Diagnostic Codes you have and post back with a list. Always worthwhile to include a Serial Number as well. It makes finding diagnostic/troubleshooting info easier. A 289C2 should be RTD-preifx. HeavyEquipmentForums
