On my 1984 4/4 car I can only find one bleed nipple on one wheel (rear nearside), the other rear wheel doesn't seem to have a bleed nipple. Is this right??

It should have, but often they seize and get snapped off by a hamfisted hobbyist! They can be drilled out with care, or you can replace the rear brake cylinder fairly easily.

Does the rear brake pipe go into the offside cylinder then out and across to the nearside? That's the only way one bleed nipple would work.

Otherwise look closely at the offside, because it may have been sheared off.

Yes that's right, two pipes are going into the offside cylinder and then across to the nearside cylinder where there is a bleed nipple. I can't find any reference to there being only one bleed point for both wheels though??

It's unusual, but back in the mists of time I do remember this being used on some cars, but I don't know if that's normal for Morgans of that era.

It could be changed to a conventional T piece to each side.

That's the system on my 1980 Plus 8. One pipe form the front to the offside slave cylinder and then another across the axle to the near side where there IS a bleed nipple.

Same on my 1972 4/4.

Totally normal and very common back in the day. Not as good as a pipe and nipple to each in theory but in practice makes no difference when you think of the brake pipe run from the master cylinder to the rear axle it makes little if any difference to plumb the rear brakes in series rather than parallel. It was as a common thing with BL cars of the day (not that that’s an endorsement of sound engineering practice ;-)).

I guess split braking systems ended this sort of plumbing. My Ford 107E had something like that.
