Here are my recommendations for brakes:
1 check levers. when you squeeze the lever you should have 2 fingers width minimum between the lever and the bar when you squeeze the brakes . Any less and they are too loose .
looking at the shoes with hands off the levers there should be about 1/16 to 1/8 inch clearance with the leading edge slightly closer to the wheel

2 scuff up the pads. If off the bike put a piece of 80 grit sand paper on the table and rub the pads on it till the surface is uniformly rough.

3 When re installing the pads make sure they mate properly with the rim. Pads usually have a slight taper. make sure it is going the right way or the pad will only contact the rim on one edge.
If the pads have a direction arrow make sure they are installed the right way.

4 Clean the rim with alcohol and then sand the sides of the rim where the brakes hit with 120 grit sandpaper or steel wool followed by cleaning with alcohol.

5 Replace the brake pads with kool stop salmon or other high performance pads.

You can check to make sure the brakes are functioning properly - both sides going in and out when you squeeze the brakes .
You should also spin the wheel and look closely to be sure the wheel is true and the rim is not dragging on one side of the caliper.
