Mine too, they either rubbed or didn't work! I can still hear and feel the regular bump bump bump and in my mind feeling it sapping my energy.
Well if it helps, I don't have that issue with mine. I made sure they set the pads properly at the 6 weeks service, although I did have the bedding in issue pretty much up to that 6 week point... I actually have a couple of good mechanics at my local Halfords.
I had cycled about 800 miles in my first 6 weeks though.
