vacuum in the unit).

pedal with average
foot pressure, hold
and start engine. If
the servo unit is working properly, the pedal will be felt to
give slightly under
foot (servo
assistance becomes
effective). If faulty replace
complete. Check valve (item 14 )
is in vacuum hose Functional check - It must be possible
to blow through in
direction of arrow.
