GENERAL INFORMATION
Rigid brake pipe: Repair
30A
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.

Note:
To make the r ivets, fit the rivet press in a vice.

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.

aMeasure the dimensions (X3) (in mm) curve after
curve, between each curve radius « centre » (1) of
the old pipe.

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.
