Product Description

The Brembo KT04534 OE Rear Disc Brake Kit combines two Brembo 09.D339.11 UV-coated rear rotors with a P50138 PRIME low-metallic brake pad set. Designed for selected Mercedes-Benz AMG applications, the kit provides a matched rear-axle replacement solution for vehicles equipped with the compatible factory rear brake configuration.

The 09.D339.11 rotors use high-carbon cast-iron construction designed to support heat conduction, thermal stability, vibration damping, and braking comfort. The UV-coated surface provides corrosion protection on exposed areas, while the ventilated construction promotes heat dissipation during repeated braking. The P50138 pads use PRIME low-metallic friction material engineered for OE-equivalent performance and comfortable operation.

KT04534 is verified for 2018-2021 Mercedes-Benz GLC63 AMG and GLC63 AMG S models with 4MATIC AWD, 2019-2021 AMG GT 53 models with 4MATIC+ AWD, and the 2021 AMG GT 43 with 4MATIC+ AWD. The GLC63 models use a 4.0L V8 Biturbo, while the AMG GT 43/53 use a 3.0L turbocharged inline-six mild-hybrid powertrain. Confirm the original rear brake configuration before installation.
