Don't give up on the Hucks just yet. It may take a period of time on the road for the shoes to wear so that their arc will match that of the drums. Once the shoes are machined into shape by the drums from routine braking, you will need to readjust the brakes. You should then see a significant improvement in stopping power. In the '40s, the brake mechanics would grind new shoes to match the drums (until they contracted lung cancer from the airborne asbestos).
