Best do an update on this one..
Not a brilliant pic but you get the idea.

Mounting of the dual reservoirs, I just used a generic mounting bracket from Rally Design and spaced it off the bulkhead on some delrin spacers.

A rubbish shot in the footwell to show the location of the adjusting cable. It's a nice smooth run from the knob which is located by the choke cable.

I've already detailed elsewhere on the forum the initial problems I had getting the car to stop with the EBC Greenstuff pads that I had fitted, these pads were an improvement on what must have been utterly shit pads that I'd bungled on to get the car rolling during the rebuild. It passed the MOT with the EBCs and some raised eyebrows at the effort required to slow the rollers. However the efficiency was there and the MOT tester builds kit and competition cars so they like to see something a bit different.....
Changing over to standard Unipart pads that I picked up at Stoneleigh made a huge improvement to the bite and feel of the brakes. After bedding them in I essentially repeated the process of nailing the brakes at speed and adjusting the bias until the rears no longer locked at low speed. After a couple of weeks use the rears feel like they need adjusting so I'd guess they are doing more work than when they were before. The next time I'm out in the wet I'll have another go and probably reduce the rear bias again.
Would I recommend it? Yes, the feel through the brakes is much improved, if a cylinder pops I can pick up a generic Land Rover replacement or drop the pennies on a Willwood or similar version. As an extra bonus the idle is much more stable than it ever was when the servo was attached.
