I prefer the factory manuals because they break down the trouble code to possible causes, how to check further and the scope of system the trouble is in. It appears there are random sensors all over the engine bay but actually they are grouped in sub-systems. The trouble code should indicate which system to start checking if not which sensor.
Don't forget new rotors and drums should be trued(cut) before they're used.
Digital cameras can pay for themselves over the cost of polaroids for recording what you're doing...or rather undoing. This works for non-automotive projects too, so if you need an excuse to convince your partner(or yourself) for buying............
