Next time you, clean off the baked on dust as you call it, put the piston under a strong magnifying lens. What you'll find is a tiny pit in the cadmium, the dust is clinging to corrosion, as the coating is damaged. How does is get damaged, crud allowed to build up in the dust seal, crud contains grit and salt which is a crystal, over time coating is worn away.
That's why these brakes need to be rebuilt every 2years or 18k. If you're riding in all weathers I recommend you do it every year.
