This product line is designed to reduce brake fade and maintain consistent stopping power under demanding conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life on vehicles such as the Pontiac Park Avenue and Cadillac Seville.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis solid rotor features a 298 mm outside diameter and a 38.8 mm overall height, fitting vehicles with a 5-lug bolt pattern and 118 mm bolt circle diameter. The drilled and slotted surface type is directional, which helps channel gases and debris away from the braking surface, improving pad contact and heat dissipation. The rotor’s nominal thickness is 11.2 mm, with a discard thickness of 9 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, critical for maintaining rotor integrity over time.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Buick Bonneville, Cadillac DeVille, Pontiac Park Avenue, and Seville models requiring a 5-lug, 298 mm rotor\u003c\/li\u003e\n\u003cli\u003eAddresses brake fade caused by excessive heat buildup during heavy braking\u003c\/li\u003e\n\u003cli\u003eReduces rotor warping and cracking through improved heat dissipation\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion on the rotor hat for longer durability\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or debris-prone conditions with slotted and drilled design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 9 mm before installation. The rotor is designed for vehicles with a 5-bolt hole pattern and 118 mm bolt circle diameter; verify compatibility with your specific make and model. The directional surface requires correct orientation during installation to maintain optimal braking performance. Use proper torque specifications on lug nuts to avoid rotor damage.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function. The rust-resistant zinc silver coating on the rotor hat enhances longevity. While no specific warranty information is provided, adherence to discard thickness and proper installation will ensure reliable service life for your Buick, Cadillac, or Pontiac vehicle.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794125127861,"sku":"HBHR-631-45009R","price":89.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63145009R_Fro.jpg?v=1774641450","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-45009r-disc-brake-rotor-rear-right","provider":"PartCatalog","version":"1.0","type":"link"}
