[edit] To adjust the position of the brake blocks

The brake blocks should not touch the tire or overlap the rim.
Loosen the Brake block using an allen key, push the arm so the brake block is pressed up against the rim.
Move it into position.
Push the arm hard while gradually tightening the allen screw.
Keep your thumb in a position to stop the brake block twisting while you tighten.

[edit] To eliminate vibration on braking

Adjust the brake blocks so they have "toe-in". That is, the trailing end of the block touches the rim just before the leading edge.
To do this, put a piece of packing between the back end of the brake bloc and the rim when you move it into position.
This means there are a lot of things to hold at once so having someone to help is a great benefit.
A piece of cardboard from a cerial box provides about the right amount of packing.
