This design improves water, gas, and dust evacuation from the rotor surface, which helps maintain consistent braking performance. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers who require rotors that balance performance and durability, specifically engineered for vehicles like the Volvo XC90.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional drilled and slotted surface enhances pad bite and helps prevent brake fade by efficiently dissipating heat and gases. The rotor measures 308 mm in outside diameter with a nominal thickness of 20 mm and a discard thickness of 18 mm, ensuring it meets Volvo XC90 braking system requirements. The rotor includes five bolt holes with a diameter of 16.8 mm arranged on a 108 mm bolt circle diameter, matching the vehicle's hub specifications. The zinc silver hat finish provides rust resistance, protecting the rotor from corrosion over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Volvo XC90\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or dusty conditions with drilled and slotted design\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake fade during extended or heavy braking\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on rotor hats for longer service life\u003c\/li\u003e\n\u003cli\u003eMaintains proper rotor thickness and fitment for safe braking operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on a compatible Volvo XC90 model and that the part number 631-27039L matches the vehicle’s specifications. Clean the rotor surface before installation to remove any protective coatings or residues. Verify that the bolt hole pattern and diameter align with the vehicle hub. Proper torque specifications should be followed when securing the rotor to avoid warping. It is recommended to inspect brake pads and other braking components during rotor replacement for optimal system performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM standards for fit, form, and function.
