In that case, you can benefit from trying an adjustment to tighten them. That failing, you could clean or reline/replace them.
Bottom line, though, is that that's one of the weak spots of the design of the brakes on the A, B/BN, and Cub. Beacuse all the tension is applied through the rod to only one end of the band, the geometry and forces at work on them will make them more effective in one direction than another. Given that the tractor is logically capable of greater speed in forward gears than in reverse, they're set up so that forward is the direction with the greater effect.
The C, H and M had a cam mechanism so that tension was aplied from both ends of the band.
Adjustment/relining/replacement (and a little roughing up of the drum as Gene mentioned) will help, but you'll never have the braking in reverse that you do going forward. It's pretty much the nature of the beast. My '47 BN stops quite well going forward and the brakes are adequate for backing just the tractor off of a trailer (10' of dovetail and ramp off a deckover trailer). Where mine show up as weak is in backing off the trailer with an implement (like my #100 spreader) behind.

I tried to use an easy out but it wasn't budging and I didn't want t
