For the BMW Z4 rear brake service, the coated rotors provide corrosion protection and a clean installation surface, while the pad compound is formulated for stable friction performance and consistent pedal response. The rotor machining process uses tight tolerances and a non-directional finish to support quieter operation and more even contact during bed-in. Part number 4502-31173 is a practical choice for a rear brake refresh on the BMW Z4.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Kit Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRear brake noise during stops\u003c\/li\u003e\n\u003cli\u003eRust buildup on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eUneven braking feel from worn pads and rotors\u003c\/li\u003e\n\u003cli\u003eLonger stopping distances caused by worn friction material\u003c\/li\u003e\n\u003cli\u003eBrake pulsation related to rotor wear or finish issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 2003-2006 BMW Z4, rear. Confirm rotor size, pad shape, and axle position before installation. The rotors are shipped dry and ready to install, so no oil removal step is required.
