Sorry guys this one doesn't add up.
There is no reason to bleed one caliper before the other beyond the fluid it shares its channel with cross contaminating the other.
The statement above doesn't make any sense. Suppose you are bleeding the RR, then go to the RF, where does this air come from that is now going to be in the RF? It isn't there. It didn't pull it in from the other line. Was the ohter line full of air? Sure hope not!
Years ago we used to do the caliper the furthest away first, and today that's still good thinking so you don't end up sucking any old FLUID into the shorter line when retracting the pedal.
On this diagonal system, uless you open the system to air via the master, allow air in to it, replace the ABS pump or open a valve in one of the lines between the mc and the caliper, the system doesn't know if you opened up a caliper or the pads are way worn! Fluid transfer is simply that; fluid transfer. If you don't allow air to become introduced into the system during the bleeding it doesn't matter which one is done first or last with regard to air- there isn't any.
Now, don't get me started on warpped rotors from over torqued lug nuts.....
