As always happens change wheel cylinders one side next month otherside goes , the LH cylinders I cleaned up and installed new Girling seals I had in garage as an experiment, looking for a reasonable wheel cylinder hone now, it was now pulling to left due to drivers side shoes all soaked in brake fluid.
The old ones on drivers side showing rust / grunge inside cylinder.
so got some red rubber grease and squirted this inside cap and cylinder end before fitting new ones , was in two minds whether to put grease on seal , decided not to
I was not happy with the location of bleed nipple and the tight bends needed on brake pipes.
So I thought I’d rotate the backplate to allow better access for bleeding and pipes.

This required a longer pipe made up from flexi but bleeding a lot better and both pipe runs on top half of hub
Bled ok and pulls up straight again , still need to change the adjusters

I'd suggest you've got the pipes attached to the cylinders the wrong way around. If you feed the supply into the lower port, then air bubbles in the system will rise and be flushed out of the upper port more easily. The pipe between the cylinders should still be the right length when you move it on both cylinders, and you appear to have enough slack in the feed pipe to be able to make it reach the lower port fairly easily.
 
Yes I see where you are coming from, but I did check the wheel cylinder first to see where the hole was. There is only one hole inside the cylinder and the supply and bleed both join it , so assumed no affect on getting air out, I left the bleed nipple in same port as received, it is a bit more accessible too without the supply pipe crossing it.
looking at the pics the other side however could be neater to avoid the pipes crossing

I know its a bit late now but I honed mine in situe. Saved quite a lot of time. Pulled the shoe clear and put a screwdriver under it, there's just enough room to get the hone behind. Not taking the springs off saves quite a lot of faff. I would say that honed cylinders plus new seals are better than new cylinders and seals. The finish on the new cylinders was poor and I think that's what had worn the seals.
 
What brand hone did you use Rob, these were TRW replaced about 3 years ago, so I have a few lying around that can be refurbished perhaps , there is a small ridge perhaps 8-10 mm from the outer edge so it’s worth a try , I used some 800 grit and a finger on the LH pair and they seem to be holding out albeit for less than a month !
