WARNING
This braking system was designed for use on a single rider bicycle. Use of this system on any other vehicle or
apparatus will void the warranty, possibly causing you great personal harm and injury.
Please use extra caution to keep your fingers away from the rotating disc brake rotors. The disc brake rotor is
sharp enough to inflict server injury to your fingers if caught within the openings of moving rotor.
If your bike is involved in a fall or crash, stop and fully check the brake function, including: the lever, caliper, and
rotor are securely attached to the bike, pads are correctly installed and functioning, the cable is operating
smoothly and the lever feels firm when actuating the brake. Always have a qualified mechanic or your
Authorized Giant Retailer check the brakes if you have any doubts.
CAUTION
Disc Brakes, calipers, rotors and pads get VERY HOT during regular use. DO NOT touch or attempt to service
the rotor or caliper, assembly until you’ve allowed for sufficient cooling to occur.
Pad thickness must be more than 2.5 mm( recommendation values). Confirm this before each ride. Keep pads
clean and free of oil or hydraulic fluid. If pads become contaminated discard and replace.
Cleanliness is a very important part of any maintenance of the Giant Hydraulic Disc Brake System. If the pads
or rotor become contaminated with oil, or if the system becomes contaminated with impurities, braking
performance will be
greatly impaired.
Ensure that cable housing is always secured to the frame and/or fork prior to every ride. Do not ride a bike on
which the cable housing can come into contact with the tires.
B) NOTICE
If you are unfamiliar with any element of assembly or maintenance of this braking system, please consult a
qualified mechanic or your Authorized Giant Retailer for assistance.
To prevent risks and potential dangers, please keep this product away from children.
