Oct 2014, Neil Williams remarked:
Braking a wheel isn't the same as locking a diff. Apart from anything
else, the locked diff still powers both wheels.

Though achieves nothing by doing so, as it is spinning.

It means some power can be transmitted as soon as adhesion returns, but
most importantly because the diff is locked the other wheel is still
getting power.
