2016-2020 Cadillac CT6 Carbon Ceramic Big Brake Kit — Brembo GT6 6-Piston Challenger The rear hats and floating

The rear hats and floating hardware in the kit are matched to the M35i rear so the EPB mechanism clamps correctly with no recalibration needed

On the D3 S8's cable-style setup we retain your OE parking-brake operation while adding real rear thermal capacity behind the 380mm rear rotor

The rotors also shed roughly 60% of the mass of the factory iron discs

That removes the biggest line item on a dealer CCB job
