This used OEM BMW brake hose carries part number 6784620 and was removed from a donor Z4. It serves as the flexible line transferring brake fluid from the chassis hard line to the rear caliper. Over time, a brake hose can crack internally or externally, leading to a spongy pedal or fluid leakage. This hose fits Z4 models with the 2.0L turbocharged four-cylinder or 3.0L naturally aspirated and turbocharged inline-six engines.
