56 BRAKE SYSTEM
CHECKING AND
READJUSTING ROAD
BIKE BRAKES
With side-pull brakes the brake arms are suspended
from a common point, thus forming an integral sys-
tem. When actuating the brake lever, both arms are
tightened by the cable, the pads touch the rim.

CHECkING THE BRAkE SYSTEM

Check whether the brake pads are accurately
aligned with the rims and still sufficiently thick (see
chapter "The brake system").
Do both brake arms contact the rim simultaneously
when actuating the brake levers? Do you get a
clear-cut braking response when you pull the brake
lever hard, and does the lever remain clear of the
handlebars no matter how hard you pull?
An accurate adjustment of the brake is achieved,
when your brake system has passed on all of the
above points.

VERTICAL ADjUSTMENT OF THE BRAkE PADS

Release the fastening bolt of the brake pad by one
to two complete turns at the most.
Push the brake pad to the correct height and align
it according to the rim before re-tightening the fas-
tening bolt to the specified torque.
Manufacturers of brakes deliver their
i
products with detailed operating instruc-
tions. Be sure to read these operating instruc-
tions carefully before you dismount a wheel or do
any maintenance work.
The brake pad must hit the rim accurately
To adjust the height of the brake pads tighten the bolt to the pre-
scribed torque
When replacing any parts be sure to only
i
use original spare parts!
After the readjustment do a brake test in
standing. Make sure the brake pads en-
gage fully with the rim when you pull them hard
without touching the tyre. furthermore you
should not be able to pull the brake levers all the
way to the handlebars. Otherwise the brake might
fail or the tyre sustain damage, thus causing an
accident.
READjUSTING AND SYNCHRONISING THE SIDE-PULL
BRAkES
With dual pivot brakes, turn the small (headless)
screw, located at the side or on top of the calliper,
until the left and right brake pad are at the same
distance from the rim.
furthermore, check whether the bolt connect-
ing the brake to the frame is still tightened to the
prescribed torque, as specified in chapter "Recom-
mended tightening torques".
Turn the knurled nut through which the brake ca-
ble passes at the brake body until the travel of the
brake lever suits your needs. To synchronise the
brake, turn the little bolt on the side of the brake
arm or the other bolt in the top area on the other
side.
BRAKE SYSTEM
Screw this small bolt until the clearance between brake pad and rim
is the same on either side
Turn the knurled nut to adjust the necessary brake lever travel
Damaged brake cables that are for exam-
ple frayed should be replaced immediately,
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 bicycle dealer.
