The R1 Concepts drilled front-left brake rotor for 1977–1989 Peugeot 505 and 604 is a black-finished replacement rotor made for that front-left fitment. It supplies the braking surface required to slow the vehicle, while the drilled pattern is intended to help vent and clear debris compared with plain rotors. Ensure the front-left part matches your vehicle's year and model before purchase.
