Troubleshooting brake issues Workhorse UFO
Up until a month ago I had issues with the parking brake locking up intermittently.
The Wabco Diagnostics software and Wabco tech support diagnosed the issue as faulty HCU. The 3rd party warranty sent an assesor out and they agreed with this diagnosis. My mechanic reckoned it qould cost about 5,000$.
When the HCU was installed the same issue appeared, my mechanic found that the wiring harness was corroded, so he replaced it. He put back in the old HCU (this was a 2012 rebuild) and all has been fine since.
The total was about 900$ in labor and 400$ for the harness. If the harness had been diagnosed first it would have been maybe 700$ total.
On a side note: The warranty company denied payment due to the corrosion and mis diagnosis. I am appealing this as there assesor signed off on it. The corroded harness I will end up paying for as corrosion is not covered.
