The rotors are machined to tight tolerances, built to G3000\/G11H18 cast iron specifications, and inspected for balance and critical dimensions before release. The 5000 Advanced Brake Pads are formulated for stable friction performance, with post-curing and scorching steps that help deliver consistent stopping response from the first stop. This brake kit is a direct service solution for BMW 640i xDrive front and rear brake replacement, and part number 4504-31059 is also a useful reference when sourcing the correct kit for this platform.\u003c\/p\u003e\u003ch2\u003eCommon Brake Service Issues\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation from worn or uneven rotors\u003c\/li\u003e\n\u003cli\u003eNoise during braking from aged pads or rotor surface wear\u003c\/li\u003e\n\u003cli\u003eRust buildup on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eExtended stopping distance caused by worn friction material\u003c\/li\u003e\n\u003cli\u003eUneven pad bed-in after brake service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 2014-2018 BMW 640i xDrive, front and rear. One fitment note lists an optional design for full cast disc brake rotors; another notes compatibility with aluminum hat rotors designed to original specifications and includes a disc brake pad wear sensor. Verify rotor style and sensor requirements against the vehicle before installation. Clean, dry rotors reduce prep time during brake service, and the non-directional finish supports a more even bed-in process.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDFC states that each rotor passes 100% inspection for critical attributes and that all vented rotors are balance-checked and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and assembled with premium shims to support consistent performance and NVH control.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":52461643301045,"sku":"HBHR-4504-31059","price":424.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_450431059_Kit.jpg?v=1777944642","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-4504-31059-disc-brake-kit-front-and-rear","provider":"PartCatalog","version":"1.0","type":"link"}
