Re: rear disk brakes
The disc brake advantage is they dissipate heat, something a
trucker knows how to avoid. I surely wouldn't use a train as an example.

Re: rear disk brakes
Exactly - and heat comes from higher braking forces. Discs are a lot
cheaper though, which is why I think they are so popular.
Incidentally, how do truckers avoid heat build up on descents ? I assume
they use engine braking as much as possible and short sharper braking
as (for discs anyway) prolonged mild braking warps them (which might
be in itself why truckers like drums - I don't know ?)

Don't forget drums on 18 wheelers work in reverse. I mean instead of
pushing the brake pedal to produce hydraulic pressure to make the shoes
brake, you push the pedal to release the air that hold the brakes from
braking. IOW, the air released that normally keeps the drums from braking
on an 18 wheeler is easier to brake with than hydraulic pressured brake
system. If you loose air in the brake lines of an 18 wheeler you lock
up the brakes and that is not good.

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.
