Used BMW Brake Master Cylinder, OEM part number 6785666, also replaces 6779680, 6776002, 6752540, 6763670, and 6770917. This genuine hydraulic component converts pedal force into pressure to actuate the calipers; a failing unit often causes a spongy pedal or fluid leaks. Fits 2.2L, 2.5L, and 3.0L naturally aspirated inline-six engines found in several E46 3 Series and Z4 models.
