I had a post up about this when I first bought my XTZ. I noticed the heat shield around the park brake cable was zip tied to high up and wouldn't protect were it needed to. I just moved it down and have had no problems since. I have added some heat shielding of my own around the rear park brake area using Thermotech wrap and it seems to help a lot. Thanks for posting this as a reminder for everyone to check your vehicle out from front to back for these kinds of problems. Be pro active and make the changes needed before you have a problem.
