I definitely learned a little thing with my XT m8000 brakes. When you have to bleed these make sure free stroke adjustment is fully out away from bars. I switched brake from one bike to a new one and had to bleed them out. Iíve never had any issue with this. When I tried to do this yesterday I forgot to put adjust all the way out and couldnít get them to bleed. Well ya big dummy it would help a lot to set the levers out so ya have some stroke to work with DUH!!!!! So for everyone starting out or not sure. If you have to ever bleed brake with free stroke adjustment make sure to set them all the way out.
