Introduction
The brake system allows you to control the speed of your bicycle,
and this function is critical to your safety. The brake system can be
difficult to adjust properly without the proper tools and training. If you
are unsure of the brake adjustment, 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. If you need more specific informa-
tion regarding your brake system, contact your Fisher dealer.
Rotor
A rotor (Fig. 57) allows the handlebars on a freestyle bike to rotate
360 degrees despite having a cable operated front brake. Since the
rotor is a connection between the brake lever and the brake, its function
is critical to good stopping power and safety.
Once a month inspect the rotor for proper function. Watch the bearing unit as you
rotate the handlebars 360 degrees. It should not move up or down, or tilt. When the brake
lever is applied, the rotor should apply the brake firmly while the bearing unit remains
parallel to the upper and lower cable stops. If the bearing unit tilts either when the brakes
are applied, or when the handlebars are rotated, the rotor needs adjustment.
To adjust the rotor, first ensure that both lower barrel adjusters are flush with (do
not show above) the lower cable stop, and the bearing unit should be resting on the
lower cable stop. Your rear brake adjustment must be made with the bearing unit in
this position.
The bearing unit should be parallel to the upper and lower cable stops. If it is tilted,
there is slack in one of the cables. Pull each end, one at a time. To see which cable has
slack at the bearing unit. Remove the slack through the barrel adjuster. When even pull is
achieved tighten all barrel adjuster locknuts.
If you are unsure of the brake adjustment, 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.
Caliper brakes
Caliper brakes (Fig. 56) are a rim brake. Rim brake information is
