If it is not messed up, it the parking brake mechanism will push equally on
both shoes. If
the wheel cylinder is frozen to the backing place and cannot "float", something
else will happen.
In any case, the leading shoe does more work, because the
rotation of the brake drum tends to "wrap" the leading shoe more
tightly against the drum.
