Work on the brake system
In general, use quick coupling type unions (it is recommended to use the same brands used to originally equip the vehicle). When
required due to dimensions (e.g. near curves) unions with a metal insert can be used. Before inserting the pipe into the union, tighten
the union itself into the threaded seat of the component (e.g. pneumatic valve), using the following values for tightening:
Table 2.22
Thread Tightening torque (Nm
±
10%)
M 8 x 1 mm 5
M 12 x 1.5 mm 24
M 14 x 1.5 mm 28
Insert the pipe into the union for the section of length L that was previously marked, using a force between 30 and 120 N, based
on pipe dimensions.
The components can be replaced (valves, etc.) as the coupling and the union permit internal rotation during unscrewing and screwing
operations.
!
New unions must be used when replacing a pipe . A union may not be reused after it has been opened.
Pipe installation
The new piping must be carefully cleaned inside before being used.
The fastening elements must completely wrap the pipe; must be in metal with rubber/plastic protection or be made out of plastic.
Figure 2.28 shows two examples of brackets with retaining springs for fixing the brake pipes along the chassis.
