4.8.2 Replacing the wheel lock

a) Replacing the spring and pull-release cable:
Unhook the pull-release cable from the adapters on the side panel as described in Section
4.5.4.
Open the screw die in the brake block (Figure 4) and pull out the pull-release cable. You can
remove the pull-release cable spring and replace it if required.
Remove the anterior tension nut from the pull-release cable and completely unscrew the ad-
justment screw. Now the pull-release cable is fully removed. Replace the pull-release cable if
required. For reassembly, proceed in the reverse order. Adjust the wheel lock as described in
Section 4.8..
b) Replacing the wheel lock handle:
Unhook the pull-release cable from the adapters on the side panel as described in Section
4.5.4.
Use a screwdriver to remove the rubber grip from the wheel lock handle (Figure 5). Loosen the
screw on the inside of the side panel until the wheel lock handle is fully removed (Figure 6).
Replace the wheel lock handle with a new part.
Mount the wheel lock handle by following the steps in the reverse order and hook up the pull-re-
lease cable. Use superglue to attach the new rubber grip to the wheel lock handle (see Section
4.7.5).
