The drilled and slotted surface pattern improves heat dissipation and helps maintain consistent braking by reducing gas and dust buildup. The zinc silver hat finish and rust resistant coating provide additional protection against corrosion, making this rotor suitable for vehicles like the Mercedes-Benz 300SD that require reliable stopping power under varied driving conditions.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air to flow between the rotor surfaces, which helps reduce heat buildup during braking. The directional slotted and drilled surface enhances pad bite and assists in channeling away water and debris, improving braking consistency. With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor maintains structural integrity and safety throughout its service life. The zinc silver finish on the rotor hat and the rust resistant coating on the disc surface help protect against corrosion, extending the rotor’s usable life. The rotor’s 5-bolt pattern with a 112 mm bolt circle diameter ensures proper fitment on the Mercedes-Benz 300SD.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Mercedes-Benz 300SD\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eReduces brake fade caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion-related rotor damage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor surface is clean and free of any contaminants before installation. Verify the rotor thickness is within specifications before mounting. Use proper torque settings on the 5 lug bolts to avoid warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check for proper directional orientation of the rotor as indicated by the directional surface design.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Mercedes-Benz 300SD. The rust resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the rotor is designed for reliable performance and consistent braking under normal operating conditions.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795653623989,"sku":"HBHR-631-63009L","price":96.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63163009L_Fro.jpg?v=1774641620","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-63009l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
