5. Avoid moving the wedge on the cable. Remove the wedge from the brake. Hold the
wedge by its lower corners while you tighten the cable clamp nut to
6-7
Nm
(Figure 10.6).

6. Cut the brake cable to length. It should not protrude past the spring (Figure 10.7).
Finish the end of the cable so that it will not interfere with the brake return spring.
If you choose to only cut the cable and not dress the end, the extended tunnel of the
wedge prevents immediate fraying of the cable.
If desired, solder the end. Or install a cable crimp, then bend it forward.

7. Insert the correct brake pads and set the pad spacers (Figure 10.8, and see Table 5
below). There should be 1.5 mm between each pad and the rim when the brake is not
engaged.
Make sure the pad carriers are oriented correctly so that the pads do no slide out when
the brake is applied.
