Just got some new Koxx browns, a fresh grind, and oh my god. My brake is amazing! haha. Took my booster off, and it got really loud (as expected) and it held way better. Also got some of those new Try-All mounts, so I don't need the stupid plastic slave washers, and my brake is perfectly flat on the rim. Spent literally 2 minutes setting the brake up! Not the 20odd I used to spend trying to get the pads flat on the rim.
