bought 2 of these to compress the caliper cylinders, both failed miserably, both bent and broke in the pivot jaw area when I had to turn them hard to compress the stuck cylinder. Maybe I asked too much of them, but they couldn't stand the intense pressure. I think that's why the crank is so short, not to over-tighten. It's probably great for woodwork or the like, but definitely can't handle high torque applications.
