The vented design and cross-drilled surface help manage heat during repeated stops, while the slot pattern helps sweep away brake dust, moisture, and gases from the pad-to-rotor interface. The zinc-plated finish helps resist rust and corrosion, making it a practical choice for daily driving and wet-weather use. This part cross-references Toyota OE numbers 42431-08050 and 42431-42080 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade during repeated braking\u003c\/li\u003e\n\u003cli\u003eRotor surface rust and corrosion\u003c\/li\u003e\n\u003cli\u003eDust and moisture buildup on the braking surface\u003c\/li\u003e\n\u003cli\u003eUneven pad contact caused by contaminated rotor faces\u003c\/li\u003e\n\u003cli\u003eRear brake replacement needs on Toyota RAV4, RAV4 Prime, Sienna, and bZ models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFits 2026 Toyota bZ, rear.
