Check brake hydraulics for leakages
Before starting the test, completely breathe
the brake hydraulics.
Then pressurize the brake temporarily (5EA)
with p = 100 bar max.

bar max
and close connection to HP pump via shut-
off valve.
A pressure drop of max 2 % (2 bar) is
permissible during a 5-minute testing time.
Low-pressure test :
Low-pressure test :
Reduce test pressure p = 5 bar and close
shut-off valve.
No pressure drop is allowed during a
5-minute testing time.
