The biggest change for me came from using sandpaper, stuck to the brake drum, to bed the shoes in.

kept the Ariel yokes in place. This allows all the BSA wheel fittings to be used . . .
BUT the Ariel forks are a little wider than the BSA so the rim had to be offset and
the wheel spindle doesn't protrude much from the nearside fork leg. I changed the
brake because I was worried about the Ariel brake fading - we lived in the Chilterns
at the time and the sidecar got used.
The Ariel half-sided brake works well enough for me but they do take some careful
setting-up, especially when new or used for any length of time badly adjusted.
Done properly, you can get quite a good contact between shoe and drum. I find
a reasonably heavy cable with a fair bit of length works better than the shop-bought
ones which are too short and somewhat flimsy. Another point I find is that wear in the
cam pivot doesn't help. Just don't expect stoppies.

I've always used original shoes and had them relined with the softest lining available.
Bedding in, I use double sided sellotape stuck to the drum, and then I cut a strip of 60 grit paper to the exact width and circumference of the drum, and stuck it on. Then you work the whole back plate/shoe assembly back and forth until you have full shoe contact with the drum.
I've also used 60 grit emery tape:

I Imagine stopping a SQ4 with one of these 7" HWH brakes can be interesting at times.
