housing block then put the cable into the cable clip.
Press the brake cam half down and close the cable clip.
Cut the excess cable
Adjust the setting using the brake lever setting key
2/Changing the friction pads
Loosen the brake cable
Remove the supporting screws from the caliper on the fork
Remove the screws that fix the friction pads or lift and pull the plate directly
depending on the model.
Remove the pads and replace them in the same way
Loosen the cam check nut, adjust the stroke using an Allen wrench then tighten the
nut.
Warning :
To maintain efficient breaking and limit wear in the rims, replace the pads as soon
as wear becomes too noticeable. A worn pad is one where the fluting or the not-
ches can no longer be seen...
The sides that run against the pads should also be watched As soon as signs of
the side opening or loss of parallelism, change your rim.
Disc brakes become hot and may cause burning, after breaking weight about 30
minutes before touching the rotor.
