Anyone know anything about disc brakes?

Yup - it has two holes near the top, and one in the tip. But is sealed - I cant see the end of the hose.

Edit:
after watching a useful video, it seems it should be pre-bleed, and has a clever auto olive system like a j-kit, but built into the shifter... so question:

If I chop the end off with the j-kit style insert, do I remove the bolt from the caliper, slide it over the hose, add an olive and an insert and away we go - or does this Direct system require a different method to create a perfect seal? #bleedingn00bwithastanleyknife
