Inspection- Coaster Brakes
Before every ride check that the brake is working properly by pedaling
backwards. The brakes should engage with less than 60 degrees
backwards rotation of the cranks (1/6 revolution). If your brakes do not
firmly engage, take your bike to your Fisher dealer for service.
If you are unsure of the brake operation, or suspect any problem,
do not ride your bicycle. Take your bicycle to your Fisher dealer
for service. It is strongly recommended that adjustment of critical
components such as brakes be done by your Fisher dealer.
Once a week check that the brake strap attachment bolt is tight and
that the brake strap is securely fastened to the chainstay (Fig. 54).
Inspection- Inter-M Roller Brake
Before every ride, make sure the Nexus Inter-M roller brake (Fig. 55)
is working properly. After about 15mm of brake lever movement, the
brakes should engage enough to stop the bike.
Adjustment- Inter-M Brake
To decrease the amount of lever travel necessary to engage the
brakes, loosen the barrel adjuster locknut, and rotate the brake cable
barrel adjuster (Fig. 55) counterclockwise. To increase lever travel,
rotate the barrel adjuster clockwise. Test the lever for correct travel.
When the desired setting is achieved, rotate the barrel adjuster locknut
clockwise until finger tight to hold this adjustment.
Lubrication
Every 3 months, lubricate your brake lever pivots with Wrench Force
®
synthetic chain lube or a similar light oil.
Lubricate brake cables with a thin layer of Wrench Force
®
synthetic
grease or a similar lubricant when installed.
Cable Installation
To install a brake cable in Shimano Inter M brakes, note the path of the old cable, loosen
the brake cable anchor bolt and remove the worn cable. Turn the adjusting barrel on the
brake or lever fully clockwise. Grease the new cable and reinstall, feeding it along the
same path as the old cable. Make sure that the cable’s leaded end is seated properly in
the brake lever body and that the housing is properly seated in the lever. After threading
the cable through the anchor bolt, follow the directions for brake adjustment in the
Adjustment section.
After the brakes are adjusted, test the brakes by applying maximum braking force to the
levers. Ensure that the cable does not slip in the cable anchor bolt.
Finally, cut the cable so that no more than 2 inches (51 mm) extends beyond the anchor
bolt. Crimp a metal cap or place a bit of solder on the end of the cable to prevent fraying.
