I bought some Kool Stop pads for the no name side pull brakes on my Giant OCR C2 and the new pads are significantly thicker. Amazingly my bike repair book doesn't go into moving the holders further away from the rims. How do you do that? There's some kind of nut on the cable, but that seemed to only reduce the distance to the rims. Do I have to readjust where the cable connects to the calipers?
