MAGNETS!
Honestly not much, just a different way of passing fluid through the system to eliminate air. Only thing I can see that they might have changed between last gen and this gen is maybe the hose sizing if they're varying between pressure and volume.
I'd hazard a guess and say pressure since the reservoir is going to be tiny under those hoods.The calipers don't see to show anything out of the Shimano ordinary. Threaded hose instead of banjo, and a 7mm bleed port.
If they have the blips at the top of the hoods, I imagine the bleed port screw is going to be directly between thumb and index finger. I can't see any easier method to do so then with the funnel, which is as @Jaap said, a one way bleed.
meh!
All brake bleeding is a ball ache to me. I can't even tell the difference between process. Pump shit in one end wait for it at the other. What's the actual diff?
