This is a complete Brembo OE replacement rear brake kit for the Mercedes-Benz CLS550 and E550, built around two 320mm high carbon cast iron rotors, a Prime Ceramic pad set, and all the fixing hardware needed to install it. Brembo's patented Pillar Venting Technology raises the rotor's resistance to cracking by more than 40% and moves heat away from the braking surface faster for shorter cooling times. The high carbon iron increases the damping coefficient over standard grey iron, lowering vibration and noise, while the NAO ceramic friction material keeps dust low for cleaner wheels.
