it's my first time to build my roadbike myself though i have built about 3 of my mountainbikes pretty well.i cant put my 105 brikes centered. likewise, the pads dont align.not like the mountainbike's, the brake pads are easily adjusted with the flexible concave adjustment cups. what should i do to correct these problems.

Loosen the mounting bolt (bolt that goes through the brake bridge or fork), center the brake by hand, tighten the bolt while preventing the brake from moving. To prevent it from moving, you can just use your hands, or if the brake has wrench flats, a thin wrench (cone wrench).

I love the modern dual pivot Shimano brakes.

First step is to install the brake, centered by hand, on the frame as Kerry indicated.

Second, close the brake with your hand and hold the brake pads properly aligned with the rim as you tighten the brake pads on the arm with an allen wrench.

Third, hold the brake closed with your hand, or with a third hand, and tighten the cable. It might take two or three tries to get it right.

Finally, is your wheel true? Spin it and see. If the two brake arms don't release evenly, you can tweek it by tightning or loosening the little screw in the top of one of the brake arms.
