2.4b Installing and connecting the front disc brakes.
Note: if you have purchased drum brakes, please refer section 2.4a
The disc brake system is supplied fully assembled and bled. It is strongly recommended that you install the
brakes supplied without disconnecting any hoses or attempting to shorten the hose
Route the hose down to the kingpost disc mount. Make sure the hose is running in a position where it will not
twist, kink, or be damaged or pinched. Also check for chaffing of the hose on the tire or the trackrod. The hose
should lead in a fair curve between the lever and the mounted caliper. If it doesn’t, it is possible to twist the
hose in its connector at the lever end until the hose runs smoothly to the caliper
(caliper above shown mounted on bicycle forks)
Mounting the Caliper
New brakes are supplied fully retracted with a red
plastic insert between the pads. With a firm grip, pull
the red insert out from between the pads (it just clips in
place).
Do not squeeze the brake lever until the caliper is
installed. If you do, the brake pistons will be
overextended and you will need a bike shop to
rebuild your caliper.
Slip the caliper over the rotor and then rotate it up to
the kingpost. Align mounting holes with those on the
caliper and fix with the supplied caliper bolts. It is
important to centre the caliper over the disc rotor using
some of the supplied caliper shim washers between the
caliper and disc mount. This is done by trial until the
correct position is achieved. We have also supplied 4
thicker washers (packed with the aluminium axle
spacers) which may be needed. The pads should not
contact the rotor unless the lever is pulled.
Fitting the shims can be a bit
frustrating, as they tend to fall out
when the caliper mounting bolt is
withdrawn. Try applying a thin film of
grease to the shims; they will stick to
each other and to the caliper body,
making it easier to make adjustments.
If you still find it difficult, the wheel
can be removed each time you change
the shims. It’s slower this way, but
much easier to work around the caliper
bolts.
Once the caliper has been centred and wheels spin
freely (without dragging), fully tighten the caliper bolts
with a 5mm Allen wrench to a torque of 11–13 Nm (97
to 114 in. lbs.) Check that the caliper is still mounted
centrally over the rotor.
Now sit down and read the instruction booklet that
came with your brakes.
Warning: If you are not confident of installing your brakes
correctly, we strongly recommended that you have a
competent cycle mechanic install your disc brake system.
Always wear protective clothing, safety glasses and gloves
when servicing this system.
