To Install And Adjust The Rear Brake
1.
If needed, remove the brake cover (Figure 11.2).
Figure 11.4. Wedge in rollers
2. If needed, roughly center the brake. Loosen the two bracket attachment bolts (Figure
11.3), center the brake, and retighten the bolts to 6-8 Nm.
3. Place the wedge in the “home” position between the rollers (Figure 11.4). Loosen the
cable clamp nut and slide the cable through the wedge. Tighten the cable clamp bolt
until finger tight.
4. Without changing the wedge location on the cable, remove the wedge from the rollers.
Move the wedge up the cable about 1 mm to compensate for cable stretch. Hold the
top and bottom surfaces of the wedge with a pliers or an adjustable wrench while you
tighten the nut (Figure 11.5). Tighten to 6-7 Nm.
Note: Do not leave the wedge in the brake while you tighten the nut; this will break the
delrin guide on the back of the wedge.
Re-install the wedge.
Do not cut the cable yet. Tuck the cable out of the way.
