Bleeding a Shimano st-rs785 and finding the fluid blocking and building up at the reservoir (part in red in below image).
What do you mean by blocking?
It’s not unusual to get a drop or two of excess fluid in the reservoir when doing a bottom-up bleed. It looks like the liquid is nearly spilling out of the bleed port hole. This causes the pads and pistons to be impossible to separate enough to run the rotor through without rubbing. If that sounds like what you’ve got, quickly dab the corner of an absorbent lint free cloth or paper towel on the port hole, and that should be enough. In theory the bleed port screw shouldn’t be pushing down on any excess liquid, it should just be sealing the port.

Had the same issue with the left one and it was solved with a gravity bleed but the right one just won't play ball.
The metal cover is held in place with two small flathead screws and has a rubber seal below that seems to create the blockage.
Anyone got any advice?
