The rear brakes turned out great, but one thing that was also needing adjusting was the Hill Holder. My brakes would lock up if I was backing up and hit the brakes, even on a level parking lot. Then they would not release until the clutch was let out past where it engaged. It was really working the drive train to get going.
I found it easier to adjust the HH by removing the spring from the HH, and that lets the cable pull out of the clutch fork some below where the clutch cable attach's. That let me put an 8 MM deep socket over the end of the cable, then with a 14 MM open end wrench hold the other nut to loosen it.
That really made a difference of when the HH releases the brakes. And it looks like you need the HH hooked up to hold the clutch throw out bearing back from the clutch fingers to keep it from turning and wearing out faster.
