Instruction manual

The brake saddle and the disc may be hot after braking, therefore do not touch
them during or immediately after riding, as you could burn yourself.
Before adjusting the brakes, check that the parts have cooled down sufficiently.
Your bicycle may be fitted with a disc brake only when appropriate
fixings are present on the frame and on the fork. If in doubt, consult a dealer.
If the brake blocks have come into contact with oil or grease they must be
replaced. If the brake disc has come into contact with oil or grease it must be
cleaned, otherwise braking efficiency may be strongly impaired.
Check whether or not the quick release lever is located on the right-hand side
(opposite side to the brake disc). If the quick release lever is located on the
same side as the brake disc, there is a danger that the lever and the brake disc
could impair one another
A worn, cracked or bent brake disc must be
replaced. Consult a dealer.
If the thickness of the brake block is less than 0.5 mm,
it must be replaced.
Hydraulic disc brakes
The hydraulic oil pressure disc brake has a fluid reservoir on the brake lever. The
hydraulic fluid is fed to the brake cylinders via a tube. The brake blocks are thus
pressed against the wheel rim via the brake pistons. This is a low maintenance type
of brake.

If the brakes do not work correctly, of if the brake blocks are worn to the extent that
adjustment is no longer possible, have the bicycle checked and the brake blocks
replaced by a dealer.
Disc brakes
General safety advice
This type of brake is fitted with a brake disc mounted on the hub and a brake saddle
on the frame or on the fork.
Have disc brakes adjusted by a dealer.
Incorrect adjustments can lead to accidents.
Carry out a braking test after each adjustment by pushing the bicycle strongly whilst
pulling the brake lever. Only use your bicycle when it can be safely braked.
Disc brakes require a ‘braking-in’ period. Braking power increases with time. You
should therefore be aware during the braking-in period that the braking power can
increase. The same applies after replacement of the brake blocks or the disc.
If you hear noises when braking, the brake blocks may be worn down to the wear
limit. Allow the brakes to cool down and have the brake block thickness checked or
the brake blocks replaced.
Be particularly careful not to touch the brake disc with your finger during installa-
tion, removal or maintenance if the disc is rotating. If you insert your fingers in the
holes in the brake disc, you may suffer serious injury.
