its only the christmas tree, so all you need to do, it take the tube out of the caliper, and then cut the little christmas tree out of the tube, the shortedn the tube so that the hole isnt in the tube no more, then put the christam tree in the hose again, then put it on your bike,bleed it, and then ride (Y)
Theres alot more stuff to do that just all that ^^^^^ but i cant be bothered to explain, sorry
