Nope, back to the drawing board. Flow is good and works as it should.

I have only been trying with a power bleed so I'm going to give the old method a go

Still can't seem to get flow to the brakes.

Is it likely to be an air-lock or something in the ABS module?

Next plan is to crack the lines on the ABS and bleed the line before the ABS (Cylinder to ABS) and then the ABS outlet to the brakes. Good or bad idea.

Yes, bleed at the ABS first; 2 input then 4 output lines. Then at each wheel in sequence, remove nipple, place thumb over hole and have assistant pump pedal while you releive air by slightly opening hole with advanced thumb technique. Once you are satisfied that fluid is moving, replace bleed valve, and again in sequence, open valve a good full turn or two, and leave open while pumping fluid with the pedal.

Then proceed with manual and power bleed as per RAVE.

I had to use my Nanocom to bleed the system before my brakes worked well.

Is the nanocom just doing the power bleed, or something else.

What do all the mechanics do that live in remote locations where it's a two dog town. Admittedly not many rovers in those towns however they generally can't pull a nanocom from their back pocket. Shorting across the ABS relay is pretty simple though....and pretty cheap.(would they even know to do this?)

The relay power bleed only runs the abs pump. The Nanocom/Hawkeye modulator bleed runs the pump and activates the inlet and outlet valves to bleed the modulators internal hydraulic circuits. The pump run method will work ok if you don't have a Nanocom, but you'd really need to bleed, go for a drive and activate Lo/HDC and do a few runs up to 30-40kmh and let HDC do it's thing, then pump bleed again.

You can disconnect the connector and close the abs circuit connections manually, or get a mate to make a box with 4 switches, which is what I did ages ago. Not sure it made any difference though.

The modulator bleed runs the modulator pump and rapidly cycles the 4 inlet and 4 outlet valves for short periods. I'd think you'd have your work cut out trying to replicate that with a box and four switches.
