For BMW X5 and BMW X6 rear brake service, this line is aimed at direct-fit rotor replacement where OE-style dimensions and fitment details matter.\u003c\/p\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003ePart number 604-31148 is a rear vented disc brake rotor from Dynamic Friction for 2010-2013 BMW X5 and 2010-2014 BMW X6 rear brake applications. The rotor measures 385 mm outside diameter with a 24 mm nominal thickness, 22.4 mm discard thickness, 75 mm inside diameter, 78.7 mm height, 16.6 mm bolt hole diameter, and 5 bolt holes. These dimensions support accurate rotor matching for BMW rear brake rotor replacement on X5 and X6 platforms.\u003c\/p\u003e\u003cp\u003eFits 2010-2013 BMW X5, rear. Fits 2010-2014 BMW X6, rear. Listed notes include optional design for full cast disc brake rotors and compatibility with aluminum hat rotors designed to original specifications; the aluminum hat rotor applications include a Disc Brake Pad Wear Sensor. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Brake Issues It May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRear brake rotor wear that has reached discard thickness\u003c\/li\u003e\n\u003cli\u003eBrake pulsation related to rotor thickness variation or surface condition\u003c\/li\u003e\n\u003cli\u003eCorrosion on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eNoise or vibration during rear braking service\u003c\/li\u003e\n\u003cli\u003eReplacement needs for BMW X5 rear brake rotor and BMW X6 rear brake rotor applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify rotor dimensions, bolt pattern, and rear axle fitment before installation. Confirm whether the vehicle uses a full cast disc brake rotor or an aluminum hat rotor designed to original specifications, and check the Disc Brake Pad Wear Sensor requirement on the applicable BMW X5 and BMW X6 rear brake setup. Always inspect pads, caliper condition, and hub mounting surfaces during rotor replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eUse the discard thickness specification as the service limit reference during inspection. The coated rotor surface is designed to help maintain a cleaner rotor appearance during normal brake service, while the vented construction supports rear brake heat dissipation in the listed BMW applications.\u003c\/p\u003e","brand":"Dynamic Friction","offers":[{"title":"Default Title","offer_id":43389573136565,"sku":"HBHR-604-31148","price":113.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_60431148_Fro.jpg?v=1774634048","url":"https:\/\/www.partcatalog.com\/products\/dynamic-friction-604-31148-disc-brake-rotor","provider":"PartCatalog","version":"1.0","type":"link"}
