Genuine 34326883447 BMW Rear Brake Hose Flex Hose OEM

The Genuine BMW 34326883447 is an OEM rear brake hose — also known as a flex hose or hydraulic brake hose — engineered to factory specifications for BMW X5, X6, X7, and related M-model variants. This is the same component installed at the BMW factory, ensuring a precise, no-modification fit and restoring proper hydraulic brake system function.

The rear brake hose serves as the critical flexible link between the rigid metal brake lines and the rear brake calipers, allowing for suspension movement while maintaining a sealed, pressure-rated hydraulic circuit. A worn, cracked, swelled, or leaking brake hose can cause brake fluid loss, reduced pedal feel, and compromised stopping performance — making timely replacement essential for safety.
