V-brake
The V-brake system is relatively simple: you brake by
means of the brake blocks, which press against the
wheel rim when the brakes are applied. If you notice your
V-brakes losing braking power, it could mean that your
brake blocks are worn out. Check the brake blocks for
wear by looking to see whether the grooves are still visible
on them. If the blocks are worn down to the bottom of the
grooves (to around half a millimetre) then they must be
replaced.
To replace the brake blocks, you need to release cable
(A)
above the brake first
(see fig. 53)
. Unscrew bolt
(B)
next, using a 5 mm Allen key. You can now remove the
brake blocks and replace them with new ones. Take care
to ensure you fit the correct type of brake block! If you buy
the wrong kind of brake block, you could damage the rim.
Make sure you fit the left-hand brake block on the left-hand
side and the right-hand one on the right-hand side.
After replacing them, check the gap between the brake
blocks and the rim. If this is excessive, you will have
insufficient braking power; if it is too small, they can rub
against the rim. Use an ideal gap of 2 mm as your starting
point. If the gap is greater than this, you can reduce it using
the adjusting screw
(A)
on the brake lever
(see fig. 52)
.
Ensure the front end of the brake blocks is slightly closer to
the rim than the rear, otherwise the brakes will squeal.
V-brakes can cause the rims to wear. This effect is
accelerated by contamination such as sand or street grime.
Accordingly, clean your brakes frequently, using water or a
brush, for instance, and have your rims checked regularly
by your Gazelle specialist as to whether they are still stable
or need replacing.
NB
V-brakes are very powerful. Do not therefore use the
front brake on its own, always use the front and rear
brakes together! Some Gazelle V-brakes are equipped
with a power modulator to apply the braking power more
gradually. This prevents the brakes from being applied
too abruptly, producing a short delay before full braking
power is applied.
