Just renewed rear drums, shoes and cylinders. Also brake lines up to the ABS modulator. However, can't get a pedal to even start bleeding. Just sounds like fresh air. Any help appreciated?

Having no brakes on a Hippo is a good thing! :flame2:

Ahem, banter aside. Have you tried various bleed screws to see if any fluid is present anywhere....even the fronts just to check? I have no idea about ABS modulators (not even looked at my Disco 2's mod), but is there a bleed screw/procedure for that part?
