• Corrosion or thread mismatch during brake line replacement

Installation Notes and Tips

Verify thread size, hose length, and rear position before installation. Confirm whether the vehicle requires rear left or rear right routing, since the listed Audi applications include both positions. Inspect the adjoining hard line, banjo-style fittings if present on the vehicle, and mounting points for corrosion or damage before installing the new hose. Brake system bleeding is required after hose replacement.
