This question already has an answer here:

I purchased a pair of tektro draco disc brakes recently. They arrived with the hydraulic lines setup moto style, with the longer line run for the left brake lever and the shorter run for the right brake lever.

I wanted to switch it to have left lever / front brake, right lever / rear brake. So, I just swapped the levers to the opposite side, but now they point resivoir end down. The only issue I have with this setup is that i have to loosen the levers and rotate them around the bar to bleed them with the reservoir facing up.

Will this cause any performance issues with braking?

    Why not just switch the brake lines? The reservoir being at the top helps air not get into the important parts on most disc brake models, as any bubbles that occur find their way to the top with use where they hang out out of the way, in my opinion running them upside down is asking for issues. – Nate W Jun 8 '16 at 21:47
  • @DanielRHicks I suspect "inspired by", but I do suspect the answers will be the same. Specifically "try it an see, it worked for me". There are a lot of design subtleties that could affect this, to the point where even the manufacturer may not know. – Móż Jun 8 '16 at 22:38
  • I would not trust hydraulic brakes with the reservoir upside-down, unless the manufacturer specifically permits that orientation. – Daniel R Hicks Jun 8 '16 at 22:41
  • @DanielRHicks I'm pretty much the opposite view, since the reservoir shouldn't have air in it and should be sealed, so it's more a "what side of the balloon has the hole" than "what if my feeder line is sucking air". But I am much more experimental than a lot of people. – Móż Jun 8 '16 at 23:07
  • I don't think its necessarily a dup, but @NateWengert's solution is the sensible one. – Batman Jun 8 '16 at 23:46
