Together, they provide a service kit approach for rear brake replacement on BMW models that require precise fitment and consistent pedal feel.\u003c\/p\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eDFC machines each rotor to tight tolerances and inspects critical dimensions to help ensure OE-spec fit and finish. The coated surface helps resist rust better than conventional paint or zinc-style coatings, and the dry-shipped design saves time during brake service. The pads are built for stable friction output and improved NVH characteristics, while the hardware kit addresses worn or corroded contact points that can contribute to noise, uneven wear, and caliper movement. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat This Brake Kit Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRear brake noise from worn hardware or pad contact points\u003c\/li\u003e\n\u003cli\u003eRust buildup on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eUneven pad wear caused by fatigued brake hardware\u003c\/li\u003e\n\u003cli\u003eLonger installation time from oil-coated replacement rotors\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency from aged rear brake components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFits 2017-2020 BMW 230i, rear; 2017-2020 BMW 230i xDrive, rear; 2017-2020 BMW M240i, rear; 2017-2020 BMW M240i xDrive, rear; 2016-2018 BMW 120i, rear; 2013-2018 BMW 320i, rear; 2017-2018 BMW M140i, rear; 2014-2016 BMW 228i, rear; 2015-2016 BMW 228i xDrive, rear; 2014-2016 BMW 428i, rear; 2014-2016 BMW M135i, rear; 2014-2016 BMW M235i, rear; 2015-2016 BMW M235i xDrive, rear; 2012-2015 BMW 118i, rear; and 2014-2015 BMW 328i, rear, with the brake configurations listed in the fitment notes.\u003c\/p\u003e\u003cp\u003eBefore installation, confirm rotor style, brake package, and production-date notes where listed.
