I contacted the disc brake caliper mfgr (Tie-Down Engr) and they said i could rotate the G4 model caliper to either the 3 o'clock or 9 o'clock position and still be able to bleed the brakes. That is probably what I will eventually do and redo the geometry of the brake lines at that time.

It looks like there's an internal manifold connecting the two cylinders. Air should migrate to the top cylinder in a 3 o'clock or 9 o'clock configuration.

If the two cylinders are connected with a manifold, then yes, you could probably bleed most of the air out of them.

I think they have to be. There is only one port where the pressurized brake fluid enters the caliper. I need to bleed ALL the air out I presume. I'm also going to rotate the inlet fitting 90 degrees to stay out of the frame.

Well now that it is spring time it's time to take out the boat!!

But wait, I still have to fix my trailer from last season's axle hub meltdown. So now I'm over on the other side of the axle to inspect the other hub and check it's condition.
