[E-Class Owner]

mechanic, and personal friend, always bled the air from the hydraulic system on the slave cyl. from below; he worked on "commission" and told me this is the fastest method. He used an ordinary trigger-pump style "oiler" filled with brake fluid and a length of windshield washer hose to link the oiler and the bleed nipple.

Now, if the lip seal in the slave cylinder is shot, you may be able to locate a NOS rebuild kit, or take the seal to an general/import car parts store and see if they can match up a seal from a wheel cylinder for a car equipped with drum brakes.

Good luck,

JR
