INSTALLATION

Brake disc assembly

ATTENTION: Consult the safety norms

Place the disc brake

A onto the hub B of an already assembled

wheel taking care to respect the direction of rotation

expressed by the arrow C on the flange of the disc. Fix the disc

with the appropriate M5 screws and tighten in a cross-wise

direction to 5.75N·m (50.61 lbs. per sq. inch) ± 5%.

Thoroughly clean the disc with ethyl alcohol to remove any

traces of grease or oil.

N.B. The disc can have four or six fixing holes.

2a, 2b:

Front/rear pincer assembly

ATTENTION: Consult the safety norms

Assemble the front and/or rear pincer onto the relative attach-

ments as shown in the figure. Fix them by using the M6 screws

D-E to a torque pressure of 9N·m (79.22 lbs. per sq. inch) ±

5%. Apply a weak thread-locking liquid.

ATTENTION: If the thickness of the relative

attachment on the fork or frame is less or more

than 8mm it will be necessary to substitute the fixing

screws with screws of the correct length.

4a:

Wheel assembly

ATTENTION: Consult the safety norms

Before assembling the wheel with the disc mounted, it is necessary to check that on the fixing screws I after the pommel H

there is the security circlip L.

External pad

3a:

Cable assembly

ATTENTION: Consult the safety norms

Insert the complete cable onto the V-BRAKE type brake

lever as indicated by the manufacturer of the lever.

The cable and the sheath must be the correct

length, bearing in mind the movement of the vari-

ous elements of the cable that must not interfere

with any moving parts of the bicycle.

3b, 3c, 3d:

ATTENTION: Cables and sheathes that are

too short could limit the ride-ability of the

bicycle and could cause serious accidents.

Position the terminal of the sheath on the sheath stop F.

Insert the cable into the grip G at X distance as shown in

the figure. Tighten the screw of the grip to a torque pres-

sure of 2.91N·m (25.62 lbs. per sq. inch) ± 5%.

Note: Leave approximately 2 cms of cable after the

cable grip F and bend it to 90° immediately after

the cable grip F.

4b:

Also check that the distance between the pads is always 2.5-

3mm as shown in the figure. If the measurement is less, exert a

light pressure on the external pad until the pad comes to its rest-

ing position. Assemble the front and/or the rear wheel as indicat-

Internal pad

ed by the manufacturer.

INSTRUCTIONS FOR USE

Preliminary adjustments and braking adjustments

ATTENTION: Consult the safety norms

Before utilising the braking system it is necessary to effectuate the preliminary adjustments

as follows.

Bring the internal pad in contact with the disc. Screwing in the pommel M, the pad comes

nearer to the disc; unscrewing it makes it move away.

ATTENTION: Also in the case of the inserted pad, check that the pommel M

is always screwed in even lightly to avoid losing it.
