GENERAL INFORMATION
Rigid brake pipe: Repair
30A
a
aShape the pipe using a bender, curve after curve,
while respecting the original shape of the pipe.
128814
WARNING
To avoid weakening the pipe, either bend once or
bend progressively by increasing the bend (that
is, by continually decreasing the curve radius).
Do not install a rigid pipe on a vehicle that may
have been bended and then unbended alterna-
tively to reach the correct curve radius.
Note:
During the bending operation, the required angle
should be passed slightly in order to compensate
for material elasticity.

II - REMOVAL OPERATION FOR PART
CONCERNED
aRemove the cover from the universal joint (1) (do not
keep).
aRemove:

IMPORTANT
To avoid any risk of triggering when working on
or near a pyrotechnic component (airbags or pre-
tensioners), lock the airbag computer using the
diagnostic tool.
When this function is activated, all the trigger
lines are inhibited and the airbag warning light on
the instrument panel lights up continuously (igni-
tion on).
IMPORTANT
Never handle the pyrotechnic systems (preten-
sioners or airbags) near to a source of heat or
naked flame - they may be triggered.
