Hi - I have a 2012 1500 4wd that is mainly used for towing. A little over 2 years ago the left front brake started dragging while towing a 20 ft camper on the way to the campground. The LF Brake was extremely hot and it seemed as if there was a little smoke coming from it. After I let it cool down the problem went away. All the way home the problem never happened again. It seemed like a collapsed line so I replaced the hose going to the caliper. For a year and a half, I had no problem. Last fall - all of a sudden it happened again. Then went away completely for 8 months. Today the problem reared its ugly head again while towing a 18ft boat (maybe 3500lb). The only think I can think of is in the last two cases, I had to do some heavy breaking due to a light changing at an in opportune time. Then the brake dragging happens. Let them cool and as long as there is no heavy braking, the issue goes away. Since I've already changed the hose and it is unlikely that a second hose collapsed after two years, is there something else that could be causing this?
