This rotor’s vented design further supports cooling during heavy braking, making it suitable for daily driving and moderate performance needs on compatible Ford, Mazda, and Mercury vehicles.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring a clear service limit for safety. The rotor’s 235 mm outside diameter and 45 mm height fit specific vehicle applications requiring a 4-bolt pattern with 13 mm bolt hole diameter and 100 mm bolt circle diameter. The zinc silver coating on the hat provides corrosion resistance, while the plain disc finish maintains a clean surface. The drilled and slotted surface is directional, designed to channel away brake dust and gases, improving pad contact and braking efficiency.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFord Escort\u003c\/li\u003e\n\u003cli\u003eMazda 323 and Protege\u003c\/li\u003e\n\u003cli\u003eMercury Tracer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis rotor is intended for use in disc brake systems on these models, addressing common braking issues such as brake fade, uneven pad wear, and overheating.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by excessive heat buildup\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to poor rotor surface design\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust on rotor surfaces\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency from gas and dust accumulation\u003c\/li\u003e\n\u003cli\u003eVibration or noise from warped or damaged rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is measured before installation to confirm it is above the discard thickness of 20 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify bolt hole alignment with the vehicle’s hub using the 4-bolt, 100 mm bolt circle pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor with rust-resistant coatings and precise machining to meet OEM standards. While specific warranty details are not provided, the rotor is designed to maintain structural integrity and performance within the specified discard thickness limits. Regular inspection is recommended to ensure continued safety and effectiveness.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51810608021685,"sku":"HBHR-631-54001L","price":76.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63154001L_Fro.jpg?v=1774642957","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-54001l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
