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.
 
The pads are hardly worn and there are no leaks from the connections.
 

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.
