Couldn’t you just put the truck in neutral and use the regular brakes?

Jake brakes change the cycle of the engine so that instead of putting fuel and air in, compressing it, and then having it explode for forward motion, it’s taking in air, compressing it to slow down the engine, and releasing it. The loud noise you hear is the sound of compressed air being released. The new models are very powerful and quiet, the old ones are much louder and truckers sometimes prefer it.
I used to work there. I made DD15 engine parts. Truckers would turn them on on purpose while driving by the plant as a thank you.
