Fasten with the bolt and nut through the clamp, but do not tighten.
Clamp the brake assembly onto the frame tube as shown. The clamp should be oriented so that the bolt runs underneath the main frame tubing.
Adjust the brake by sliding backward or forward as needed before tightening. You will need to pull the brake handle backward to move the brake to engaged position (see next image).
With the brake in engaged position, handle back, slide the brake forward until the post is just touching the tire. Mark this position on the frame. Then rotate the handle forward to disengage the brake, and slide the brake forward about ¼ from the mark. Now tighten the bolt.
Once tightened, engage the brake to verify its function. The brake post should push into the tire about ¼ inch, or half the diameter of the post.
