Product Description

The Brembo 09.A959.21 is an OE-equivalent rear rotor for the Mercedes-Benz ML350 and ML550 (OE# 166.423.04.12), combining Brembo's Pillar Vented Technology with a cross-drilled surface for stronger heat management than a standard vented rotor. The PVT design alone boosts resistance to thermal cracking by more than 40% compared to conventional vane patterns.

Brembo's UV coating covers the braking surface and hub, protecting against corrosion while keeping the rotor's finish clean over time. As a direct OE-equivalent part rather than a performance upgrade, it ships with a fixing screw kit for straightforward installation and is sold individually.
