The self-energizing servo brake action is designed to function most effectively with the car moving forward, you have inherently less brake action in reverse, all other things being equal.

I sometimes wonder if any of the modern linings for drum brakes as effective as the old asbestos-containing linings. And as originally built these brakes were yet further optimized by having linings of different frictional properties for primary and secondary shoes; today we mostly find the same lining on both shoes.
