Hi all,
Sympathies to cdnp6, don't be put off mate. It's not as painful as it sounds. I am an amateur mechanic and pulled the lot out of my dual circuit LHD on a pitched gravel drive using jack stands, brick props and not the finest tool kit I've ever seen. It was cold, too. My car had been sat for 11 years in a disused, seaside cow stable, so things were not at all well.
I spent time cleaning the components carefully, having bought seals kits front and rear plus master and remote servo kits. They all came with diagrams and instructions that I found fairly straightforward to follow but I consulted all my books carefully beforehand for a good mental image. The state of the system depends on the microclimate where the car was stored. Dank, horrible? Dry, fair? The vacuum hoses, diaphragm valve and pipes were never replaced on mine despite all of the above.
You have a supplier locally (check your PM) for brake parts. Member ianp6man in the UK handles NADA cars regularly and might have bits you can use. If mild corrosion/scoring of servo and master bores, you can - like I did - possibly sort it with a cheap honing kit for your drill and then fit the new seals with nothing further. The servo I found was easy enough to understand, overhaul and fit once I spent a while looking at fitment and layout before attacking it with the spanners. In the end I only replaced a relative minimum of perished parts (2006) and my MOT guy remarked (2008) how evenly the brakes read on his meter. Good luck!
