how semi truck trailers don’t just roll away when disconnected from a semi truck
In: 8
So, the last 2 responses talk about the brakes and how they’re designed to fail-safe, that is, when they fail, they fail into breaking mode, and that’s all true.
What I’m not sure was mentioned was that, when properly disconnect, trailers also have landing legs towards the front that are extended when parked and retracted while driving, and, well, things in legs tend to stay put, even when there are wheels on the other end. Unless the load is extremely unbalanced
