Hydraulic brakes
Gazelle bikes can be equipped with hydraulic disc brakes
(fig. 56)
or hydraulic rim brakes
(fig. 57)
.
A disc brake consists of 2 moving brake blocks. A
reduction in braking power can be an indication of air in
the brake lines; you need to make your way to your Gazelle
specialist for this.
If you have hydraulic rim brakes, check the brake blocks on
a regular basis. If the blocks are worn down to the bottom
of the grooves
(to around half a millimetre)
then they need
to be replaced.
Unscrew the brake cylinder mount top bolt
(A)
first using a
Torx T25 wrench and remove it. Unscrew the bottom bolt
(B)
next using the same Torx wrench so the brake cylinder
can rotate by a quarter turn. You can now remove the brake
block and replace it.
Once you have replaced the brake blocks, you press the
brakes against the rim so the brake blocks are positioned
parallel to the rim. Check the brake blocks to ensure they
press straight on the rim. Take care to ensure that the brake
units are not skewed, but aligned to each other.
Press the brake lever carefully and tighten the bolts once
the brake blocks are pressed in around 2 mm from the rim.
Observe the specified tightening torques!
NB
• Brake discs must be kept free from oil, grease or wax!
• If you have traces of oil on the levers or brake lines,
you need to make your way as soon as possible to your
Gazelle specialist, since this can indicate a leak!
Coaster brake
If you notice a reduction in the stopping power of your
coaster brake, then refer to your Gazelle specialist.
Maintenance and any repairs of this brake system are
specialist jobs which can only be done properly by a
specialist.
