brake fluid leak 92 850i manual

cant seem to find the source of my brake fluid leak......checked all calipers and lines.....reservoir fills and brake pedal still goes all the way down.......anyone experience any of this type of issue......please help

Have you bled the system since adding fluid? Once air gets in, you gotta get it out or the pedal will never firm up.

i have since found the problem, ......it seems that the rubber grommet underneath the reserve bottle was busted and leaking brake fluid......i have replaced and bled system and all is now well....thanks alot 02540ico for the tip
