The brake levers must always remain clear of the handlebars. You should not
even be able to pull them all the way to the handlebars in the event of an emer-
gency stop. If this is the case, however, observe the following chapter “Synchro-
nising and readjusting”. A correctly adjusted brake is only ensured if all of these
checks have been made successfully.
DANGER!

Brake cables which are damaged, e.g. frayed
(e)
, must be replaced imme-
diately, as they can otherwise fail in a critical moment, possibly causing a
crash!

Adjusting the position of the brake pads relative to the rims requires a
considerable degree of skill. Replacing and adjusting the brake pads is a job
best left to your SCOTT dealer.
DANGER!
G
Have your rims regularly inspected and measured by your SCOTT dealer.
Synchronising and readjusting
Almost all brake designs have a bolt located next to one or both brake callipers
for adjusting the initial spring tension
(f)
. Turn the bolt slowly and watch how
the gap changes between brake pads and rim.
Adjust the spring in a way that the gaps are equal on either side with an unap-
plied brake and the brake pads touch the rim simultaneously during braking.
The position of the brake lever where the brake starts to act, also referred to as
pressure point, can be adjusted to the size of the hand as well as to individual
convenience by readjusting the brake cable. Make absolutely sure you cannot
pull the brake lever all the way to the handlebar grip. With an unapplied brake
the brake pads should not be too close to the rim sides, otherwise they could
drag along the rim during riding. Before making this adjustment, observe the
notes in the chapter “Brake lever reach adjustment”.
RIM BRAKES

have two brake arms mounted
separately on either side of the rim. When actuating the brake lever, both arms
are pressed together by the cable, the pads touching the rim.
The friction generated by braking causes wear to the brake pads as well as to
the rims. Frequent rides in the rain and dirt and on uneven ground can acceler-
ate wear on both braking surfaces. Some rims are provided with wear indica-
tors, e.g. grooves or circular indentations. If the rim is worn down to the point
where the grooves or indentations are no longer visible, they need to be re-
placed. Once the abrasion of the rim has reached a certain critical point, the rim
may break under the tyre pressure. This can make the wheel jam or the inner
tube burst, both of which can cause an accident. Risk of falling!
Functional check
Check whether the brake pads are accurately aligned with the rims and still
sufficiently thick. You can judge the wear of the brake pads by the appearance
of grooves.
If the pads are worn down to the bottom of the grooves
(c)
, it is time to replace
them. Be sure to observe the appropriate instructions of the respective manu-
facturer.
See your SCOTT dealer and ask them to examine the remaining thickness of the
rims when you have worn through your second set of brake pads at the latest.
Your SCOTT dealer has special measuring devices for determining the remain-
ing thickness of the rims.
The brake pads must hit the rim simultaneously, first touching it with the front
portion of their surface. At the moment of first contact the rear portion of the
pads should be a millimetre away from the braking surface. Viewed from the top
the brake pads form a “V“ with the trough pointing to the front
(d)
. This setting
is to prevent the brake pads from screeching when applied.
