For the brake genius out there.

Adjust your rear drums up until there is constant scraping of the shoes on the drum or I was told adjust until it locks the wheel and then back it off until the wheel moves with moderate pressure but can hear the brake shoes on the drum

93 I have gone as far as I dare, I think its far enough the hub couldn't be turned but with the rim back on it turned with the motor and no excessive dragging noises.
The drums were a PITA to get off and trying to turn the drum is near impossible with the slippry diff. Will have another go in the morning when my work mate gets here. Backing the adjuster off concerns me, its a shizzen to get to.

Are you blocking it before or after the LSV? I believe the LSV returns to the master so you could have a dodgy LSV (proportional valve)

Yep NN the rubber hose to the diff all the rest are pipes.
