WARNING:
1. Riding with improperly adjusted brakes, worn brake pads, or
wheels on which the rim wear mark is visible is dangerous
and can result in serious injury or death.
2. Applying brakes too hard or too suddenly can lock up a
wheel, which could cause you to lose control and fall. Sudden
or excessive application of the front brake may pitch the rider
over the handlebars, which may result in serious injury or
death.

care in becoming familiar with these brakes and exercise
particular care when using them.
4. Some bicycle brakes are equipped with a brake force
modulator, a small, cylindrical device through which the brake
control cable runs and which is designed to provide a more
progressive application of braking force. A modulator
makes the initial brake lever force more gentle, progressively
increasing force until full force is achieved. If your bike is

equipped with a brake force modulator, take extra care in
becoming familiar with its performance characteristics.
5. Disc brakes can get extremely hot with extended use. Be careful
not to touch a disc brake until it has had plenty of time to cool.
6. See the brake manufacturer’s instructions for operation and care
of your brakes, and for when brake pads must be replaced. If you do
not have the manufacturer’s instructions, see your dealer or contact
the brake manufacturer.
7. If replacing worn or damaged parts, use only manufacturer-
approved genuine replacement parts.
