After you remove the bleed screw you will be left with the part the bleed screw fit into. You need to use an 8 MM allen key/wrench and screw that out. It is in very very tight. Once you unscrew that part the res will come right out. The little tube on the side is just a press fit, but keep track of the little o-ring as you pull the res to the side and up to take it off.
