The Brembo big brake kit for 2009-2015 BMW 7-Series rear applications replaces the OE rear hardware with a four-piston billet caliper and a two-piece 380x28 mm rotor. The drilled nickel rotor improves heat dissipation and pad cleaning, fitting as a direct rear upgrade to reduce fade and deliver firmer, more predictable braking under sustained loads.
