-- Place control module without canting it onto hydraulic unit.

Sealing rings are then brought into their end position.

-- Bolt hydraulic unit and control module with new inner Torx bolts supplied.

A new control module may be assembled on an already used hydraulic unit twice at maximum in order to guarantee the seal of the elastic gasket.

A control module which was once in driving operation must not be installed a second time.
