Replacing The Brake Blocks; The Power Modulator - Batavus Nova Versa Bedienungsanleitung

T E C H N I Q U E

REPLACING THE BRAKE BLOCKS

1. The brake blocks must be replaced
if the slanting grooves are worn away
(29). Rims have their own unique char-
acter and the blocks mounted form a
safe unit with them.
Because there are many different types
of brake blocks, we advise that you
always consult your Batavus dealer
before replacing them. We also recom-

of brake blocks to him.
However, we provide the correct order
of operations below, for experienced
amateur mechanics.
2. Turn the cable adjusting screw on
the brake grip inwards to slacken the
cable (30).
3. Push the brake arms towards one
another (31).
4. Remove the brake cable (32). Now
you can easily loosen the bolts which

When mounting and adjusting new

brake blocks they should be 1-2 mm
from the rim.
5. Secure the brake cable again. The
brakes are correctly adjusted if the
brake grips can be squeezed no further
than half of the distance to the handle-
bars. If you can squeeze them further
in, adjust them by tightening the cable
adjusting screws on the brake grips.
6. If the brake is not adjusted tightly
enough, in the case of the V-brake you
can also use a hexagonal key to loosen
the cable clamping bolt (A) and pull up
the cable slightly (33). This same bolt
is also used for replacing the cable, if
necessary.

THE POWER MODULATOR

In some models, the brake power of
the V-brake is regulated by a 'Power
modulator' or brake power dosage
unit (34). The modulator mechanism
handles extreme brake power from the
(32)
brake grip. This helps to prevent sud-
