This part is listed by BMW as BMW part number 34311157206 (34-31-1-157-206) and is described as OEM Brake Master Cylinder for E30 325e, 325i, 325is coupe and sedan (1987, 1988, 1989, 1990, 1991) and E30 318i/325i convertible (1987, 1988, 1989, 1990, 1991, 1992, 1993).

Only for cars with ATE master cylinder - Converting from Girling to this ATE version is possible, but you will also need the ATE fluid reservoir. 

This OEM ATE brand Brake Master Cylinder is a high-quality replacement for your failing original-equipment master cylinder. 

The master cylinder controls the distribution of brake fluid through your entire braking system, so even a small leak from a failing part can cause poor brake pedal feel and inaccurate brake modulation.  If you've found your brake pedal travel to be getting longer, particularly when sustained pressure is applied, a thorough inspection and likely replacement is highly recommended.
