Here is some help to narrow down the right adapters. Line them up with the hose bars all in the same direction organized from big to small as shown below. Note there are two duplicate sets as shown by the red squares.
1. Start by eliminating any adapter that does not have threads on the end. That is D and I.
2. Eliminate the adapters with tall shoulders. That is A, B (two of them), C.
Now you just have E, F, G, and H left.
G has the smallest diameter threads on the end. That is the adapter you use for the caliper. Eliminate H.
Now you have E and F left. There are two adapters that are the same. That is E and that is what you use for the brake lever.
