A week or so ago we had a nice sunny ~45degF winter day so I was outside doing an oil change on my 2017 Ram 1500 @ ~47K miles. I tested the parking brake and then noticed the parking brake cable was sagging a bit when I was under doing the oil change. Ughh. The levers that stick through the backing plates aren't moving rearward all the way. Not enough that the P-brake is engaged, but enough to allow the brake cable to droop. Really sucks too because I do exercise the P-brake from time to time, but obviously not enough for the rust belt. The truck has also been treated with Krown and sprayed with Woolwax and Fluid Film by me this past fall. I got under the truck today and freed them up with some spray lube and a pry bar, but they're still not 100% right given if the P-brake pedal gets mashed again, the levers will take a 'manual adjustment' to release all the way. I likely contaminated the P-brake shoes with spray lube too as I had to shove the spray lube straw into the rubber boots around the linkages through the backing plates to get things moving. One of my buddies has a 2016 Ram 1500 where this happened to him a year or so back. He had an extended warranty that covered it and it was like a $1200 repair per the dealer write up with all new backing plates and P-brake hardware. Crap design. You basically have to use your P-brake about daily, year around if you live in the rust belt and don't want this to happen to your Ram.
