With bearings you can pull them out and measure them, unless it's a custom part (looking at DT Swiss and the 1526 bearing in the 1501 gen2 wheelset...). Custom parts are another thing. I really don't like Shimano brakes since if anything goes wrong, you replace a caliper or a complete lever. Well don't even want to try them, mostly because of their lack of modulation and wandering bite point, but this serviceability is a big part of it all. Sram is better in this regard. But not great, they've dropped the ball when it comes to suspension spare parts compared to a few years ago. But at least they have service manuals!
