This rotor uses a grooved braking surface and coated finish to improve wet braking behavior by helping expel water and brake dust from the contact area. For BMW rear brake service, part number 150.3466.54 provides the specified dimensions and construction needed for applications such as BMW 528i xDrive, BMW 528xi, BMW 535xi, BMW 525xi, and BMW 530xi.\u003c\/p\u003e\u003cp\u003eThe Black Z range is intended for drivers who want a replacement rotor with a more technical surface design and corrosion-resistant coating while maintaining OE-style fitment. Part number 150.3466.54 also cross-references Bosch 18042 and Brembo 09.B313.11 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by heat buildup during repeated stops.\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency in wet conditions.\u003c\/li\u003e\n\u003cli\u003eSurface corrosion on exposed brake rotor faces.\u003c\/li\u003e\n\u003cli\u003eBrake dust accumulation on the friction surface.\u003c\/li\u003e\n\u003cli\u003eRotor replacement needs for worn rear brake discs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rotor dimensions, hub bore, bolt pattern, and minimum thickness before installation. This rotor is a direct-fit replacement for listed BMW rear applications, including BMW 528i xDrive and BMW 530xi fitments. Confirm the vehicle’s brake specification matches the 320 x 20 mm rotor requirement and the listed rear position before service. Part number 150.3466.54 should be matched to the paired rotor reference when replacing brake components on the same axle.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eThis rotor is ECE R90 approved and marked accordingly. Zimmermann’s Black Z line is engineered as a regulated replacement brake rotor with coated corrosion protection and application-specific dimensions for the listed BMW models.\u003c\/p\u003e","brand":"Zimmermann","offers":[{"title":"Default Title","offer_id":53534298898613,"sku":"BKND-150.3466.54","price":165.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/ZI_150346654_Fro.jpg?v=1792132549","url":"https:\/\/www.partcatalog.com\/products\/zimmermann-150-3466-54-disc-brake-rotor-rear-or-rear-left","provider":"PartCatalog","version":"1.0","type":"link"}
