Figure 2
Remove the two 8-32 nuts securing the brake body to the brake base. Once the
brake body is removed a large nut attached to the motor shaft and the motor
shaft will be revealed. The nut/shaft will be allowed to move freely. If wind or
gravity force is present on the antenna the nut/shaft may start to turn. If it turns,
the second person should steady the antenna movement until the new brake is
installed. Lay aside the brake body, brake cover, and connecting wire until later
instructions. Refer to Figure 3. Retain removed hardware for later use.
