CHECKING, ADJUSTING AND BALANCING
VBRAKES
V-brakes consist of separately mounted
brake arms on the left and right side of the
wheel. When the brake arms are pulled to-
gether with a cable the pads rub on the rim
generating friction.
Function check:
• Check that the brake pads are properly
aligned with the rim and that they have
sucient thickness. This can be seen by
checking the transverse grooves in the
brake pad. When these grooves are worn
down, it’s time to change them.
• Additionally the front portion of the brake
pads should be the first to touch the rim.
Once touching the rear portion of the pad
should be one millimeter away from the
rim. This v-shaped orientation helps pre-
vent the squealing of the brake pads.
• Both pads must simultaneously hit the rim
when the lever is pulled
• The brake lever must exhibit a reserve in its
travel. It should not pull up to the handle-
bars even during emergency braking.
Make sure that the pads touch
the sidewall with their entire
surface. Otherwise brake failure
or wheel lock could lead to an
accident. Also make sure that
the surfaces of the brake do not
touch the tires. Incorrectly set
brake pads can cause tire rub-
through leading to a tire failure.
