The Brembo GT big-brake kit for 2017–2023 E300 and E350 sedans (excluding 4MATIC) pairs six-piston calipers with cast two-piece 380x34 mm rotors in drilled form, finished yellow. Supplied as a matched front caliper-and-rotor set, it replaces factory front hardware with larger components and two-piece rotors to support heavier braking requirements while excluding all-wheel-drive 4MATIC models.
