I was also taught that disk brakes have less unsprung weight - important to
the sports car crowd. Also disk brakes cost more than drum brakes from a
new car standpoint.

Subject: [MV] disc brake pressure, et al
Disc brakes do require more overall pressure to work. That's why they have
large or even multiple pistons, piston area may be 6 times as large, giving
6 times the pressure. The sole advantage of discs is that they use most of
their circular travel to give off heat while only a small section is being
heated by friction.
Using a pinion brake as an add on should be trouble free, since it's braking
will be in addition to the stock drums- the drums will prevent the one
wheel from spinning faster than the other, afterall, you still have just as
much braking in the drums as ever. Adding a pinion brake will not add
horsepower to the spinning wheel, only add more surface area to the brake
system to dissipate heat.
And as far as one wheel spinning backwards, what is there in the stock
system to prevent it? Yet the issue is never raised unless pinion braking
is mentioned.
