You can't always trust the trailer brakes to hold 80,000 pounds by themselves. It even says on the red button Not for Parking. I would still put some chocks and dolly down. Plus you can't trust that someone won't crawl under and back your trailer brakes off.
OK to leave trailer brake applied without a trailer?

Good luck backing off the brakes if they're set.

But still a good idea. -
When we ran idle shutdown timer on newer T800's, all the guys had to do to bypass it was unplug the park brake switch. The light blinked all the time, but shutdown never occurred.
mathematrucker and Hulld Thank this. -
If you had this type trailer and the air leaks off your rolling away.
In my opinion the toggle switch method that @spsauerland gave you to fool the computer in to thinking “the brakes aren’t set when they actually are” is the cleanest, easiest and by far the safest way to achieve the result you want.mathematrucker and spsauerland Thank this. -
Fooling outside air temp works on some too. Need truck specifics.
