You beat me to that trick JonnersJon Tilson wrote: ↑Sun Sep 10, 2017 7:21 pm That's because your bleed screw is below the inlet on the slave. If you reverse them it will bleed more easily.
When I do 1850's I just run a rubber pipe from the bleed screw venting into the master reservoir. Few pumps soon has all the air out.
You'll know next time....though I have often mentioned this trick before. Its sooooo cool when you do it first time...

It would have drip bled on that set up as well, just keep m/cyl topped up and no pumps needed

Marinas used to have the same problem
