Im trying to learn more about trucks and have a couple questions:
Is there a specific switch to dump air out of the front and rear suspensions?
When I set lets say the trailer brake does that raise the suspension?
If I pump the breaks and all the air goes out of the tanks does that lower the suspension?
Air suspension question?

When you set the trailer brakes some dump the air on the trailer which would lower it.
Last question only if it has a leak after the leveling valve will the air suspension drop from lack of air.krpv Thanks this. -
Yeah I meant the truck and trailer
So when Im lowering the 5th wheel Im dumping the air on the drives? -

If parking in bad wind, dump the tractor air with the in cab switch and pull your red knob to dump the trailer. it should be less bouncy in the wind this way.
