34. Grease the brake pads and drop them into the hub shell with the larger edges facing outward from the same side of the hub shell.

Tip 1: 37:40 Standard cup and cone wheel hub:
1. To adjust, unlock the hub assembly by turning a cone nut counter clockwise while holding the locknut on the same side.
2. Loosen the hub assembly by turning the cone nut counter-clockwise while holding the opposite cone nut with another wrench, which effectively widens the distance between the two cones making the hub assembly more loose.
3. Tighten the hub assembly by turning the cone nut clockwise while holding the opposite locknut with a wrench, which effectively shortens the distance between the cones making the hub assembly tighter.
4. When finished adjusting, lock the hub assembly by turning the cone nut clockwise while holding the locknut on the same side.

Tip 2: To start from a stop with a coaster brake use your foot to push off. Remember to bring a screwdriver with you for the reaction arm in case you need to repair a flat tire and remove the rear wheel.
