==Hand Brake Cable==
The handbrake is controlled by a cable and a return spring attached to a lever which is part of the brake expander. The cable end and spring are visible from above the rear brake rotor with the wheel removed. The brake is set when the lever moves forward, and released when it moves back.

==Brake Shoes==
The shoes are attached to the backplate by pins, and held in place by springs. The brake expander is located at the top of the rotor. The handbrake adjuster is located at the bottom.

==Hand Brake Adjuster==
The distance of the handbrake shoes from the inside of the rotor is set by turning the adjuster wheel, one notch at a time. If the slack in the brake cable is not excessive, the handbrake can be adjusted to release when the handbrake lever is down, and to start to grab when the lever is raised about half-way (~ 5 clicks on the lever).

==Inspection==
The brake shoes can be inspected for minimum thickness and condition of the shoes. Other parts can be cleaned, and should be reasonably free of rust. The brake shoe shown at left is worn, the shoe lining has separated and was loose inside the rotor.
