Used OEM BMW brake master cylinder, OEM part number 6871455, sourced from a donor vehicle. This component converts brake pedal force into hydraulic pressure to actuate the calipers. A failing master cylinder can cause a spongy pedal, fluid leaks, or reduced braking performance—symptoms that this replacement addresses directly. It comes from a 2.0L or 3.0L turbocharged BMW application (diesel or gas).
