Finally riding a big boys bike
My latest thinking on grease for coaster hubs, after putting around 10,000 miles on later Bendix hubs over the last few years, is that for 99% of coaster-brake users it does not matter what they put in them as they are not using them much, and when they do they are not putting any heavy stress or abuse on the hub or brake.
For the very few who do something serious or extreme with a coaster brake hub, they should not use high-melting point grease, as it is a plus to have the grease able to flow when the hub gets warm or hot so it can flow back into the braking areas as quickly as possible after hard use, to keep lubricant that has been squeezed or burned out where it is needed.
A bone-dry coaster brake that has had all it's lube squeezed and burned out of the braking area, will lock up quickly or instantly in an emergency situation and will be very hard to control. If you are going 20mph to 40mph down a hill, especially a hill with turns and you can not control your rear wheel locking up then it is far more likely you are going to get into trouble than if you can have some sort of control over how the brake works and locks up.
For those reasons get high pressure grease, but have it be light and not high temp, and it may be good to have a bit of a radius or bevel around the edge of the shoes to help get lube between them and the inside of the hub shell.
This rider weighs well over 200 pounds and has Bendix hubs laced into large diameter 27" and 700c rims, and as a sole means of braking(not the smartest thing I know) rides them down long fast paved grades every ride over 20mph and often enough over 30mph. So far, far more strain on the hub and brake than a child or teen riding around their city block, someone on a path beside a beach or a collector parading a classic around. That what is behind my comments on Bendix coaster brake maintenance and setup.
