Fitment Notes

• Rotors (09.R103.11) fit the 350mm front brake configuration on X164 GL-Class and selected W164 ML-Class and W251 R-Class platforms only. Models with smaller 330mm front rotors (ML320, ML350, ML450) are not compatible with this kit.
• R-Class (W251) fitment applies to 7-passenger configurations only; 6-passenger R350 models use a different front rotor diameter.
• Replaces Mercedes-Benz rotor OE# 1644210512 / A1644210512 / 1644211412 / A1644211412 and pad OE# 1644202220 / 164420262064.

Features

• Complete front axle brake service in one box - matched rotors and pads eliminate guesswork and ensure system-level compatibility.
• 350mm UV-coated, internally vented rotors offer full-surface corrosion protection including internal venting chambers.
• High-carbon cast iron rotor construction reduces noise, vibration, and harshness under everyday and heavy-load driving.
• NAO Ceramic brake pads deliver low dust, quiet operation, and extended service life suited to luxury SUV driving conditions.
• Multilayered ESE (Elastomer-Steel-Elastomer) shims on the pads dampen vibration and reduce brake noise at the pad-to-rotor interface.
• Ceramic compound undergoes a pre-scorching process at the factory, reducing break-in time and initial fade.
• ECE R-90 certified components - meets or exceeds Mercedes-Benz OE safety and performance standards.
• All mounting hardware and fixing screws included - ready to install out of the box.

Product Description

The Brembo KT00025 is a complete front brake service kit engineered for Mercedes-Benz X164 GL-Class SUVs and selected W164 ML550 and W251 R350 models equipped with 350mm front rotors. It bundles two 09.R103.11 UV-coated, internally vented rotors with a P50063N NAO Ceramic front brake pad set - components that are factory-matched and validated to work together as a system. Replacing individual components piecemeal risks mismatched wear rates and inconsistent brake feel; this kit eliminates that risk with a single, engineered solution.

The 350mm high-carbon cast iron rotors provide excellent thermal management under the demanding stop-and-go and highway conditions typical for these larger Mercedes SUVs. The ceramic pads complement them with low dust, quiet operation, and a ceramic compound that resists fade and reduces break-in time thanks to a factory pre-scorching process. All hardware is included for a complete, ready-to-install front axle brake service.
