Assembly of caliper “International Standard”
Hold the caliper close to the disc brake mount on the front fork /
frame, with the rotor placed between the brake pads.
Screw in the two M6 fixing bolts, but just a few threads.
Note: the lower bolt for the front caliper is shorter!
Now squeeze the brake lever, so the rotor is clamped by the
caliper.
The space between the caliper and the disc mount has to be filled
up with washers.
Make an estimation how big the gap is, so, how many washers are
needed. Try !
For both the upper and the lower caliper fixing bolts.
Example:
If the gap is approx. 1 mm., you may need 4 washers of 0.25 mm.
thickness.
Put the washers between the frame/fork mount and the caliper.
Use a 5 mm. Allen-key to tighten the M6 fixing bolts.
Note: the lower bolt for the front caliper is shorter!
Pull the brake lever to see if the brake pads are actuated well.
If the procedure has been followed well, the caliper (and brake
pads) is set parallel to the rotor and the rotor is exactly in middle of
the brake pads.
If necessary, release the bolts that fix the brake caliper to the fork
and remove or add washers.
Don’t forget to tighten the fixing bolts again.
Use washers of 0.25 or 0.5 mm. thickness for each bolt
to set the caliper (brake pads) parallel to the rotor and
to set the rotor exactly in middle of the brake pads.
Threads of new bolts have been coated with blue
material that prevents that bolts come loose.
Always use Loctite
TM
Primer (#7649) and Loctite
TM
blue
Removable Threadlock (#242) or similar material on
thread of these bolts during
re-assembly.
Recommended tightening torque: 9 Nm.
Make sure that the brake pads are well centered and
balanced.
