Are hydraulic disc brakes reliable enough for remote touring?

Modern hydraulic disc brakes are extremely reliable and require less maintenance than mechanical systems in normal use. The concern for remote touring is that if they do need service (fluid leak, damaged hose), the repair requires specific tools and knowledge that may not be available. Carry spare pads, a bleed kit if you know how to use it, and consider learning basic hydraulic service. For truly remote expeditions, some riders still prefer mechanical discs for their field-serviceability with basic tools.
