This is a complete Brembo OE replacement rear brake kit for the W213 Mercedes-Benz E-Class and C257 CLS, pairing high carbon cast iron rotors with a Prime low-metallic 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 low-metallic friction material delivers firm, consistent bite tuned to match the original equipment.
