Curious about your code 314. I'm working on a 5500 with the same code and had a burning brake on the left side motor. Went through the troubleshooting guide but everything is checking out fine. Replaced the bad brake assembly and all seemed well on the test drive until the code popped up again. When watching the analyzer for the ECR1 and 2 I noticed that the left motor brake will apply when the code pops up but not the right side as it seems to freewheel to a stop. What did you finally come up with for the solution to the 314?
