leaving air brake parking brake on?

[farmerSmurf]

is it safe for the air system to leave the brakes engaged for long periods or would it be better to use chocks or blocks? I was thinking maybe the pressure on seals and stuff would degrade over time?

When your parking brakes are engaged there is no air pressure.
Great big killer springs hold the brakes on.
Nothing to degrade.

Even with the parking brakes on, with me its force of habit to chock the wheels. Too many years driving green stuff with parking brakes fixed by National Guard mechanics

Your mileage will really drop with the parking brake on
I've driven a bass boat with the anker down. It was real slow. I also ran the same boat with the trolling motor on the front still down in the water. Nearly ripped the mounts off. Double Doh!
If my mom were still alive, she would say it runs in the family. She once drove us kids from Dayton to Indy with the parking brake on. When we got home, she said she would have to have dad get the car checked because it smelled bad.
I don't know how many times I have have driven my S1800 across town just to look down and see the parking brake handle and slap my forehead. That is why I haven't adjusted the parking brake. Thank goodness I don't have air brakes.

You need a routine and stick to it. The bus I just picked up has hydraulic brakes. I have never had hydraulic brakes on a vehicle that big. My routine is simple and I do the same thing every time. When I come to a stop, I shift into neutral, then pull the parking brake, then turn the key off, then pull the lever that is connected to the fuel injection pump that kills the engine. Not sure what it is called. Do the same thing every time and you won't forget anything.
