The Brembo GT front big brake kit for 2014–2018 A250, 2014–2019 CLA250, and 2015–2020 GLA250 models swaps in six-piston cast calipers and two-piece 365×34 mm drilled rotors finished in red. The drilled two-piece rotors improve cooling and gas evacuation, while the cast six-piston calipers increase pad contact for firmer, more consistent braking under repeated or demanding stops.
