M&G brake system

[Jeff Miller]

The M&G systems I've seen installed are tapped into the pressure output
of the drive-axle R-12 Brake relay valve, which is unsafe and illegal
per FMVSS-121.

I did meet a man who claimed that the damage to the front of his
Wanderlodge was due to a severed air-line from his coach to the toad
reducing his braking effectiveness without notice, causing him to rear-
end another coach.

The drive axle on these coaches is responsible for roughly 70% of your
braking.

To install it correctly you would need to install a Trailer Protection
Valve / circuit like big trucks have.

Get a non-invasive system.

Although I had been a fan of proportional systems in the past, in
reality the only thing that is really useful IMO is a towed-vehicle
braking system that will apply the towed-vehicle brakes in a panic-stop
or abrupt stop. Causing them to brake the combination during long
grades and other stops risks wheel lockup or damage to the brakes, and
isn't necessary. I've gotten to prefer a good system which will apply
towed-vehicle brakes only when needed, and a system that is not
invasive to the dinghy nor the coach is IMO a huge advantage.
