Is it called a Jake Brake? That loud pap pap pap sound they sometimes
make when they are slowing down? Just curious...

I'm not a Diesel truck driver but that's what I've always heard them
called, Jake Brake. Sounds like someone blowing through a trumpet
or a huge truck f*rt when they decend a long hill or grade. I assume
they are actuated by playing games with the valves someway. I'd be
curious to know just how it does work.
