I just measured two pair of Tektro levers, one is an R200 Short pull lever set with 21 mm between the pivot and cable anchor and the other an RL520 long pull lever set which has 31 mm between the pivot and cable anchor. So, I have to conclude yours are "long pull" levers and will work best with V-brakes or "MTB" disc brakes. They should have too low leverage to work well with mini-Vs or road disc brakes.

I once tried using those Tektro long pull levers with road caliper brakes and very quickly found out the lever pull effort was much too high.
