My 650J emergency brake has unexpectedly locked on two occasions without my engaging the lever. After turning the engine off for a few minutes and restarting the dozer, the brake will release. Has anyone experienced this? If so how did you fix it?
What if any codes are showing?
I don’t recall the code number, but it indicated a fault with the emergency brake solenoid or harness. This is confusing because of the intermittent and short duration of the problem. I am out of town now and don’t have access to the machine. I will confirm the exact code tomorrow.
Start looking for bare wire, chafed or mouse chew, maybe a bad ground first.
