Again, I have no idea what you're talking about. What brakes do you have exactly? There are only a handful of manufacturers (Shimano, SRAM, Tektro/TRP, Hope, maybe a couple others). And no, you shouldn't be losing anything. Bleeding is easy: you take connect a hose to the caliper, and a cup to the level/master cylinder, and pump some new fluid in there with a syringe. (In practice, it's somewhat fiddly and can be a little messy if you're not careful.) There's no parts to lose, except the screw that seals the master cylinder, and maybe the bleed port screw on the caliper if it doesn't use a nipple.

They're Tektro. That "in practice its somewhat fiddly" bit sounds like where I am.

I'll go canvas my options with some other stores. Who knows? Maybe I'm being sold a line of guff here?

(and its a Merida 200 not a Movida. I was having a bad hair day)

I have Tektro on one bike. They work fine, but maintenance on them is more of a pain than Shimano. I'm probably going to swap them out for Shimano later, because the Shimano brakes on my road bike are so much easier to work with.

Your brakes use mineral oil, and you can use any kind of mineral oil you want in there: https://www.youtube.com/watch?v=63VIuPiX3CA
