I can tell you one thing that I notice seemed to be standard in all their brakeset.
Replace the pads, and possibly rotor.
Pads wear out stupidly quickly, the rotor might be fine, but there's a chance it may be poorly made, I swapped mine for the Shimano Ice Tech rotor, which have a noticable improvement (felt much smoother).
Bit annoying, as the brakes itself are great, let down by crap pads adding to the cost.
