But I also found "Disc Brake Pad Advancement Procedure" in SRAM manual. I followed that procedure in a modified way (I performed it with the pads installed). This procedure probably made the pistons to keep a more advanced position (maybe 0.1-0.2 mm?). I got visible relief, thus, I'll give it a test for a ride or two.
It looks like disk brakes are not that simple at they seem to be...
I would never consider bicycle components that rely on DOT fluid “simple”, though, like anything, once you get some experience working with them it’s pretty straightforward. Though SRAM hydraulic brakes are notoriously more finicky than others.
