Is there any reason why Shimano never makes any mention of degassing mineral oil prior to using it in a brake bleed? I've been bleeding brakes for a while now, and I found it interesting that Avid makes a big deal out of degassing DOT fluid before introducing it into the brake system, while Shimano doesn't even mention it.
I recently took a red hose-clamp off one off an old Avid bleed kit and installed it on the syringe hose that i use for bleeding Shimano brakes, and thus I can degas the mineral oil in a similar fashion.
I can't tell how big of a difference it makes, but there is definitely air dissolved in there, so I just found it odd that Shimano doesn't have it as a step in their brake bleeding procedure.
