Product Description

The Brembo 09.A958.21 is a UV-coated, internally vented, cross-drilled front brake rotor designed as a direct OE replacement for the Mercedes-Benz W166 ML-Class and GLE-Class platforms. Spanning model years 2012-2019 across multiple trim levels - from the ML350 BlueTec diesel to the GLE43 AMG - this rotor covers a broad range of 4-Matic AWD configurations on a shared chassis. Built to Brembo's OE manufacturing standards, it matches factory dimensions and mounting specs exactly, with no modifications needed.

The 350 mm cross-drilled disc combined with Brembo's Pillar Venting Technology delivers superior thermal management compared to standard vented designs - a meaningful benefit given the weight and power outputs of these SUVs. Full UV coating across the entire disc, including the ventilation chambers, eliminates pre-installation rust and extends rotor service life. Note: this rotor is not compatible with vehicles equipped with the optional Sport Brake System (Code U29) - confirm your vehicle's brake configuration before purchasing.
