Product Description

The Brembo KT04523 OE Rear Disc Brake Kit combines two 09.D532.13 high-carbon rear rotors with a P50138 PRIME low-metallic rear brake pad set. Designed for compatible Mercedes-Benz E-Class and CLS-Class applications, this matched rear-axle package provides an OE-equivalent replacement solution for vehicles equipped with the specified factory rear brake configuration.

The 09.D532.13 rotors measure 360 mm in diameter and 26 mm in thickness and feature internally ventilated, two-piece Co-Cast construction. High-carbon material is designed to improve damping, reduce vibration and noise, and promote effective heat transfer. The coated rotor surface adds corrosion protection to exposed areas. The P50138 pads use PRIME low-metallic friction material and include pad accessories and preparation for an electronic wear indicator.

KT04523 is verified for the 2018 Mercedes-Benz E400, 2017-2018 E43 AMG, 2019-2022 E450, 2019-2022 E53 AMG, 2019-2021 CLS450, and 2019-2021 CLS53 AMG. The applicable vehicles use 3.0L turbocharged engines, with RWD or 4MATIC AWD depending on model and trim. Confirm the vehicle's rear brake configuration and 360 mm rotor specification before installation.
