Any chance you can throw up a few pics of this process please? I have tried a few times and created a mess. Where as a traditional top down gravity bleed works just fine for me.if they have a bleed port on the caliper (i dont use shimano junk, so i don't know) then try reverse bleeding them.
fill a syringe with fluid and push it from the caliper up to the lever end... i always get a nice solid bleed that way, and its the direction air wants to travel usually. i have had chain stay mounted brakes on a couple of bikes and never had air in the system.
