The pads look pretty work and dried out. When was the last time they were replaced? Maybe placing the thicker concave spacer between the pad and canti arm will bring the arm angle out to come closer to a right angle with the straddle cable when the pads contact the rim.
Since brakes are simple levers comparing canti arm lengths and the angle the straddle cable sits at (when pads touch the rim) is an easy thing to do. See included diagram for specs. Andy
All three, although the rare servicing only because it's been out of commission for quite a while until I replace the destroyed front wheel. Normally just elements and salt. It was sitting outside a bit more than usual during some garage renovation work - has a nice home now. I wouldn't ride with the chain that bad! Pads are probably about 3 years old.
