I call it too late for them, at least for this set of brakes. When I'm able to find an adapter, they'll go.
The bicycle and the brake pads should actually go the other way around.
Next up should be rear brakes, get rid of the wheel lock at the back, mount gear switchers on the stem (because none of the frame tubes are actually round) or leave them and add cable housing instead and finally repaint the whole frame (maybe matte black?). As an extra I'd change the seat, drill-and-weld-nuts for a second bottle holder and hear your opinions on everything as well. Oh, and fix the whole cabling mess for the lights already (2+1 in front and right now only one at the back) to make it less visible (8V 3.2Ah battery in the bag with cables running from there).
As a side note, I'm not looking for any expensive or unneeded modifications, but just to keep everything simple and practical. It would be my daily commuter for school on 2 kilometers of gravel and another 18 on "highway". Then all the way back.
