This Brembo Prime kit replaces the front brakes on the C218 CLS550 with two 360 mm vented, cross-drilled discs and a matched set of low-metallic pads. The discs are cast from high carbon iron, which damps vibration better than standard grey iron and pulls heat off the braking surface faster, so the brakes stay quieter and cool down sooner after hard use. A UV coating protects the hat and vanes from corrosion, and the disc fixing screws are supplied in the box. The pads carry counterweights and an anti-squeal shim and are prepared for a wear indicator, though the sensor itself is not part of the kit.
