What to replace after using WRONG hydraulic fluid Tektro Auriga Comp hydraulic brake. I needed to add fluid to my brake, and decided to do a bleed. I used DOT 3 fluid instead of mineral oil (Very stupid me). after a few days my brake went dead (there is not fluid, must have escaped through a damaged seal). 

Question: What seals/things must I replace in the brake - I do not wish to purchase another brake (but will purchase correct fluids in the future)? Do I replace all the seals/rubber parts, or are there more parts to replace? Can I buy a 'kit' that contains all the parts needed to replace?
Every non-metal part touched by the fluid could have been damaged by it, and none of it is available as service parts other than the hose. Especially given you're already seeing evidence of the seals degrading, replacing the whole thing is all you can do.
