I - REFITTING PREPARATION OPERATION
aAlways replace the aluminium pedal pad each time it
is removed.
II - REFITTING OPERATION FOR ALUMINIUM
PEDAL PAD
aCheck that the pedal is at ambient temperature.
aCheck that the surface of the pedal is clean.
aActivate the pedal bonding surface with some paper

Note:
If only the pad is being replaced, allow the pedal
to cool.
Note:
The bonding area must be clean, and free from
finger mar ks and fabric deposits.
Note:
It is essential to activate the surface and to wipe
in the same direction: there is a risk of contami-
nating the bonding surface when wiping.
Note:
Do not use the same paper to activate the sur-
face and to wipe the surface.
Throw the paper away after each use.
