Twice I had a sticking slack adjuster (two different wheels/brake) cause a heat buildup noticeable with my TPMS temp. First, was only going about an hour from home to a resort, and about five minutes from destination, while going through a Main Street area with lights, thought I smelled tire/brakes. All seemed normal, continued on, and my BIL was there and was helping guide me as I backed in, and I saw him going wheel to wheel, feeling/smelling. Got a mobile mechanic out, said all looked ok, but needed a proper shop to look at it. Was headed to NIRVC anyway, so had them check, they found nothing, and leaving there, about 10 miles out, a different one stuck, and this time set off TPMS temp (vs. me just noticing it) and there was smoke in the cabin.
I now have two TPMS monitors on my dash, bot reading the same sensors on the tires. One I keep on the PSI screen, the other I keep on temp, and monitor both regularly, not just waiting for an alarm, and really focus on them after any time I used the brakes more than just a tap (I use engine brake regularly, switching between lo/med/hi as needed).
