Hydroboost is simple.
Treat the m/c and the calipers/slave cylinders like any other vacuum system.
Only difference is that your booster works off the power steering pump and not the engine vacuum. The big round boosters you are used to seeing are nothing more than a large vacuum diaphragms. Your booster is all it needs to be to give you power from the steering system.
Keep it in good shape with good fluid and you should be good to go.
If the booster needs to be replaced, get a rebuild or a kit.
They should be readily available.
GM also used them on Astro vans.

If you need info an putting it back together, you would need to contact someone with an early year TR.
Lots of help around here.
