III - REFITTING OPERATION FOR THE ALUMINIUM
PEDAL PADS
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
soaked in HEPTANE.
Wipe immediately with a clean and dry cloth.
Remove the protection around the pad.aBond the pedal pad (8) to the pedal (9) by pressing
on the right-hand side.
Press the pad to ensure bonding.
IV - FINAL OPERATION
aRefit the clutch pedal switch (see 37A, Mechanical
component controls, Clutch pedal switch: Re-
moval - Refitting, page 37A-52) .
aRefit the brake pedal switch (see 37A, Mechanical
component controls, Brake pedal switch: Re-
moval - Refitting, page 37A-42)

Note:
If only the pad is being replaced, allow the pedal
to cool.
Note:
The bonding area must be clean, and free from
finger marks 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.
