My solution to attach cheap Febi 01817 brake bomb to -89 750i.
First there is female thread coupler attached to the bomb with loctite 577, then o-ring washer and adapter for hose. At the another end is compression olive for the original tube, sadly you have to cut the original tube. Bomb is attached to car with original mounts, drill the spot welds from old bomb(do NOT drill too deep on the bottom part, if the bomb is intact, the high pressure will release). Upper bracket can be mounted under adapter, lower bracket is glued with wurth power tack.
I have now tested this solution and it works like new(as I got my brakes and LAD installed)! I had bad pulsating on hydraulic system and all symptoms are now gone, it was so bad it affected engine idle also plus that nasty feeling at brake pedal. Cheap fix, Febi bomb and 20 euros to hydraulic shop.
