Now fill a bleed syringe with approx. 20ml mineral oil and an air cushion of approx. 4ml.
Bleed the brake system by unscrewing the bleed screw and now insert the bleed syringe
into the brake lever body unit via the opening that has become free. The bleed syringe
must be inserted into the brake lever body unit in such a way that the opening released by
unscrewing the bleed screw is completely sealed.
Then create a vacuum in the venting system by slowly pulling the piston of the bleed sy-
ringe and operate the brake several times. Repeat this process until no more air bubbles
rise into the syringe. The system should then be free of air.
