Speculatively speaking here: Front break pads and rotor on C50 are exposed to elements and dirt, which probably facilitates build-up of grime and break pad dust. Rear break pads and drum are enclosed, minimizing the effects of elements on the wear and tear, but at the same time, doesn't it prevent or impede break pad dust from escaping the drum?
Front disk break cleaning is a straightforward process: scotch-brite (optional) + spray + wipe = clean. Rear drum break is a lot more involved and requires removing rear tire, disconnecting pedal linkage, etc. Can the dust be blown away with an air hose?
Is cleaning a drum break even a thing? Should I go rather drink a beer?

I don't think theres a way to blow the brake dust out without removing the tire. There is a small gap on the top of mine, but that means its also the only way the dust can escape. I don't want it blowing back up in my face.
I can head East or West, it doesn't matter as long as it's on 2 wheels.
