The drilled and slotted design helps reduce brake fade by allowing gases and heat to escape, while the zinc silver hat finish and rust resistant coating protect against corrosion. This product line is tailored for drivers seeking reliable braking components compatible with specific Ford and Mazda truck models.\u003c\/p\u003e\u003ch2\u003eProduct Details and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking. The slotted and drilled surface enhances pad bite and helps clear water and debris from the rotor surface, maintaining consistent braking performance. With a nominal thickness of 26.1 mm and a discard thickness of 24.5 mm, this rotor meets the necessary specifications for safe replacement. The zinc silver hat finish and rust resistant coating provide additional protection against environmental wear, extending the rotor's service life. The rotor is designed with five bolt holes (1\/2-20 diameter) on a 114.3 mm bolt circle diameter, ensuring proper fitment on compatible Ford Ranger and Mazda B-series trucks.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for Ford Ranger models\u003c\/li\u003e\n\u003cli\u003eCompatible with Mazda B2300, B3000, and B4000 trucks\u003c\/li\u003e\n\u003cli\u003eIdeal for addressing brake fade and overheating issues\u003c\/li\u003e\n\u003cli\u003eHelps resolve uneven brake pad wear and rotor warping\u003c\/li\u003e\n\u003cli\u003eSuitable for restoring braking performance on vented rotor setups\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 24.5 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify bolt hole alignment with the 114.3 mm bolt circle diameter and use the correct lug nuts for the 1\/2-20 bolt holes. Directional rotors must be installed following the indicated rotation direction to maintain optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for fit and function.
