Good question, I don't have any lights displayed, but to your point it will not come on either, but by the time it did you already knew your brakes were fubar'd
I would consider a non-power brake setup with the Wilwood MC before I went Vac, always there when you need it.
For the teflon hose, any Aeroquip will be fine as long as it is teflon lined, -6, 6ft might be marginal, I would buy extra in case you have a goof, always good to have on hand, should be a price break over 10 ft, the Jegs number is good, I use "Race Parts Solutions" quite a bit also.
