D-Series Rear Brakes/Park (Bugged)

The D-Series rear brakes, or at the very least the Heavy Duty rear brakes, seem to be bugged. They heat up incredibly quickly, and fail to hold the vehicle in place at all. While I understand the particular truck I used in my example is far from light at nearly 3 tons; it most certainly should not be behaving in this manor. As well park seemingly has no effect on the truck, as if the gear simply does nothing, I don't remember the park gear previously being reliant on the brakes in the game so I must assume this is an entirely separate issue.

Did you even watch the video, I show there are no mods installed ten seconds into the video...?

 

Just copied your exact specs, brakes work fine on my end in safe mode. Id try a reinstall or something unless @Goosah has any better suggestions

 

The safe mode was a good tip, just for sanity check, but when you use the spec in the video it still happens. I've attached a copy below. I've tried safe mode, no safe mode, cache clear, verify integrity it always happens.
