Gravity
Brake caliper turned so the nipple is at the absolute top and loose then wait.
It also helps if you have the wheel cylinders pushed tightly in as there is less fluid or air to displace, if you have a little air pocket then gently
tapping the caliper will help to dislodge this and the bubble will rise.

you should always start with the biggest fluid capacity furthest away from master cylinder
normally the nsf.. then osf then furthest rear and nearest rear...
the best way to bleed it if you have the patience is to gravity bleed..

This seems to be a common problem with rear calipers. On mine the calipers were reversed so the nipple was at the bottom.
I had to remove it to bleed it as described in last post. Worked a treat.

Mines at the top,
Fronts fine But the rear is a nightmare,

Run braided line into rear of the handbrake, then out of handbrake to rear split then to rear, is on Sierra discs

Well you certainly have made it tricky for yourself.
Intergral masters you cant easibleed and hydraulic handbrake thats going to be a pain to gravity feed.
cant you do it the old fashioned way and get someone to pump the brakes...?

Effectively by fitting a hydraulic hand brake you have created a dead leg in the system with no way to bleed it, best way round it is to insert a
Tee piece into the line going from the hand brake master cylinder (close to the cylinder) and screw a bleed nipple into the 3rd leg of the tee.
You can then bleed this using the single stroke method, open the nipple (don't open too far) operate the hand brake, and with the handbrake
still on close the nipple, then repeat 3 or 4 times.
Then do the same for the foot brake.

I thought for the IVA or even the MOT the handbrake must be mechanical not hydraulic? or is this a race car?

Same applies to MOT though too, Al. Hydraulic handbrake should be a fail... though these things can sometimes depends on your tester.
Other things worth trying for bleeding: ensure the rear calipers are higher than the master cylinder, help get gravity on your side; leaving the pedal
wedged down hard can help encourage air bubbles to migrate to the bleed nipple; disconnecting the fronts on the bias bar will help get more pedal
travel into the rear master cylinder; use a vacuum bleeder to suck the fluid through.
