Andrew, I have GRX levers and Ultegra actuators. It acts as if
these are
not compatible. The levers on both front and rear will not "pump" the
brake pades close enough to the discs so that they actuate with
almost no
pull. Instead they pull almost all of the way to the bar.

Should be, uses same pads/hose fitting kit and so on, and appears to be
same calipers broadly from Tiagra to Dura Ace, though Cues is I believe
doing its own thing! Aka less performance more simple design.

What I was trying to discover was if the 10 speed GRX levers didn't
have the capacity of the 11 speed Ultegra actuators. That occurred to
me in a dream.

But since they are compatible it must be air in the

system. The thing that bothers me is that all of my previous disk
bikes had hard front and back brakes. This setup has the same pull on
front and back and the front is a straight shot up and bled without a
problem.

Because the rear caliper line entry is at an unusual angle. The front

Need to remove the rear caliper form the frame so it can be at the
lowest point in the system, line pointing up. Rap the caliper with a
tool handle while purging the fluid. It has air in the nooks and
crannies of the caliper.

Roger, what is doubling down? I had a dent in the top tube and it went away. I showed you the SCIENCE of how that could happen and you believe it to be fake science? Frank is NOT a mechanical engineer and Liebermann isn't even an engineer of any sort. Flunky is on this newsgroup at least 100% during what would be working hours and he has showed us his account where he said that he rode TWO 200 mile rides wityh climbing in them at around 20 mph rides. If you believe ANY of these guys you have to ask yourself why.

My brain injury caused seizures and not as you seem to conceive - the inability to think. The seizure stopped the ability to post and that was treated successfully with medication. So the question arises, what has happened to your ability to think?

You think that there was a dent which just disappeared.

That did not happen. Or a metaphysical event interceded with

If you leaned against the door of your truck and it bent inwards, so you pulled the liner off and pushed it back out with a "clang!" would you be talking impossible metaphysical events or that you were just imagining it?

 That's not a high-carbon steel tube, dumbass.
 

True, but the principles are the same across steels as a group.  The relative numbers vary from one steel alloy or temper finish to another.
