I just had an old Specialized Sequoia built up with Suntour Superbe brakes and I'm very impressed with the quality. Mine haven't had any problems with centering. I put Suntour brakes on the bike because they have more clearance for tires and fenders than the Tektro 539 double-pivot brakes that came with the frame. I was initially concerned that the Suntour brakes would not have adequate stopping power, but those fears proved to be unfounded. The bike stops great with excellent modulation, helped I'm sure by the use of Kool Stop salmon pads. They are also very nice looking brakes.
