The Brembo Big Brake Kit for 2003–2008 SL500/SL550 and 2009–2012 SL550 rear applications provides a four-piston cast caliper with 328×28 mm two-piece drilled rotors in red. The drilled rotor faces help evacuate gases and water; the two-piece assembly separates friction surface from the hat to simplify service, supplied for the described rear fitments.
