This used OEM BMW brake master cylinder cover, part number 7363246 (also replaces 7398081), is a genuine replacement for the cap that seals and protects the brake fluid reservoir. It fits models with 2.0L turbo four-cylinder or 3.0L six-cylinder engines, both gas and mild-hybrid versions. A cracked or missing cover can allow contamination into the brake fluid, so this simple piece helps keep the hydraulic system clean and functioning.
