This OEM ATE brand Brake Master Cylinder is a high-quality replacement for your failing original-equipment master cylinder on early E30 325e, 325i, and 325is models without ABS, model years 1984, 1985, 1986, 1987 (Production date up to and including 4/1987).

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.
