Moffett Brake Issue

[Bonnydoon]

G'Day from Downunder.
Is there a specific way to bleed the brakes on a Moffett 7040. I am getting fluid and pressure at the front pedal. Tried everything to get some action at the back brake pedal at the rear, absolutely nothing, no resistance. Is there a trick to bleeding this dual system?

I've a leak at the back so I just ignore the front pedal and bleed at the nipples at the back by pto cover, 1 at once.
I run a length of see through 6mm hose from nipple up into the reservoir and pump it through until all bubbles stop then do other side.
Rough.

edit - have you bled to the trailer brake valve under the right side of the cab? 3 bleed nipples there on the standard tractor.

Thanks Nearly. I like the clear 6mm hose idea. No I havent bled the trailer brake bleeds. It will be a week or so befoer I can try both suggestions. Will let you know how I get on.
