This is the brake line / self-leveling distribution piece found at the rear of 2002, E21, E30, E36, E28, E34, E24, E32, E38, and Z3 models. This piece takes the incoming brake or hydraulic fluid line and splits it off to each rear wheel. It's a common spot of leaks and failure on older cars thanks to rust inside the piece or on the connecting lines. If you notice leaking brake fluid on the subframe or the underside of the rear floor is damp, it could be leaking from the distribution block (or a leaking differential input shaft seal). Don't do any rear brake line work without having one of these on hand to replace or have as a spare!
