This procedure applies to copper pipes diameter 4.7
mm.
REPAIR
I - PIPE PREPARATION OPERATION
a
aCut the pipe to the recommended length using a
tube cutter (see Garage equipment catalogue).
aPut the nuts or bolts on the pipe before forming the
rivets.
II - MAKING THE RIVETS
a Equipment required
compressed air nozzle
Tightening torquesm
brake pipe bolts8 N.m
underbody unions
(female/male)6 N.m
Note:
This procedure does not apply to:
-hybrid pipes (pipe + hose),
-pipes with diameters 6 mm and 8 mm.
WARNING
To avoid causing a breakdown in hydraulic brake
circuit , do not squash or bend the rigid pipe
when cutting.

aFit the pipe in the rivet press (see Garage Equip-
ment Catalogue).
aAdjust the length of the pipe to be shaped.
aTorque tighten the press end piece(40 N.m).
III - CHECKING THE RIVETS
aVisually inspect:
-the uniformity of the rivets' diameter,
-the rivet centring in relation to the pipe shaft.aVisually check that the internal diameter of the pipe
is not oval-shaped.
aCheck that the diameter of the end panel is not oval
shaped using a sliding calliper.
Correct diameter if (X1) = (X2)
IV - PREPARATION OF THE PIPE BEFORE
BENDING
a
aBlow inside the pipe in both directions using a com-
pressed air nozzle.
aPut plugs on the bolts or nuts at the ends of the pipe.
aPut the original pipe on a flat base plate that is the
length of the pipe.

Note:
Impurities may spread inside the pipe while the
rivets are being made.

V - CHECKING BENDING
aCheck the out-of-roundness of the outer diameter at
the centre of the curve radius (2) using a sliding cal-
liper (the out-of-roundness of the outer diameter is
correct if it is less than 10% flattening):
-nominal diameter of the pipe: 4.75 mm,
-minimum diameter after bending: 4.30 mm.VI - REFITTING THE PIPE
a
aTorque tighten the brake pipe bolts (8 N.m).
aTorque tighten the underbody unions (female/
male) (6 N.m).

Note:
When refitting the rigid brake pipe:
-respect the original routing as much as possi-
ble,
-adjust the pipe routing by hand when fitting
inside the clips.
WARNING
Contact points between the rigid brake pipe and
the surrounding components could cause dam-
age to the pipe. In order to avoid these contacts,
adjust the pipe routing by hand.
