The Tektro's are miserable. I didn't realize until I switched them out. New pads are a good short term solution, but investing in a new set of calipers is a good idea. I got Rival brakes, and they've made a significant difference. In addition to saving weight, the Rival brakes have beefier springs which I can control much better. You can find them for very cheap online and they're a breeze to install at home.
