2010 Jeep JKUR towed brake issue

We have the brake buddy system from our MH to the Jeep. I set it up as per instructions. Do the 5 air purge tests and make sure there is about the thickness (palm to back of hand) of a hand distance from the handle of the brake buddy to the seat of the Jeep. The last few trips it seems the PS front caliper starts sticking. Had the two front calipers replaced March of 17 when we dragged it down to Fla and it hung up, making the PS front rotor glow bright orange. Arrived in Fla yesterday, running errands today and again the same caliper is dragging. Let it cool as it was smoking a bit. Took it out to dinner and Walmart later today and no issues. I replaced all 4 sets of brake pads and rotors myself before we left over the last 3 months or so. What gives? Any thoughts/ideas?

Thanks

Bob

    It could be the rubber hose to the caliper is letting fluid go through under pressure but is blocking the back pressure after you take your foot off the brakes.

    Had the same RF caliber stick on my 2015 JKU. All 3 other calibers OK. Solution was to have the dealership investigate. They replaced the RF caliber, hose, and grind the rotor. Pads were OK. Total mileage at this time was 9970. I suspect salt air corrosion and lack of caliber sliding pin lubrication. Jeep has never been off road and is my senior citizen wife's car. Current mileage is 13500................
