Re: rear disk brakes
We use our gears and the Jake Brake, that holds the exhaust valves
open, scaring the heck out of the people around us. If we are going to
be going down hill we start out slow and try to maintain a slow speed.
Being very tired one night, way out of my log book, I was slowing for
the scales at the bottom of Cajon Pass, that's on Interstate Fifteen
dropping into Riverside, California, as I turned off the freeway I
missed my sift from sixth to fifth that's the change into the two speed
under, rather than try to double clutch and grind her in, alerting every
cop around, I thought I could use just my brakes to slow it from there
at about fifteen miles an hour to the walking speed they want us to go
thought the scales at, as I went through the scales I could see my
trailer brakes were on fire, luckily they felt sorry for me and let me
have a green light, where I could blow that fire out.

Re: rear disk brakes
That's an additional safety device, it pressurize the parking brake
spring in a separate can at the end, you may see:
http://web.syr.edu/~wposcarl/AirBrak...Photo-Copy.jpg to
release the shoes to move. We still use air pressure to stop, just like
you use hydraulic fluid pressure to stop.
