This rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The directional surface incorporates both drilled holes and slots, which aid in expelling gases, dust, and water from the braking surface, maintaining consistent contact between the brake pad and rotor.\u003c\/p\u003e\u003cp\u003eWith a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor provides a durable braking surface while indicating when replacement is necessary. The rotor’s 364 mm outside diameter and 55.5 mm height are engineered to match factory specifications. The five bolt holes, each 14.6 mm in diameter, and a bolt circle diameter of 120 mm ensure secure mounting. The 70 mm center hole diameter allows for proper alignment on the hub.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with a vented rotor design. This combination is intended to improve braking efficiency by enhancing heat dissipation and maintaining cleaner rotor surfaces. The silver plain finish provides corrosion resistance while maintaining a professional appearance suitable for Acura MDX and TLX vehicles.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Acura MDX and TLX\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps prevent brake pad glazing by maintaining a clean rotor surface\u003c\/li\u003e\n\u003cli\u003eReduces brake noise and vibration associated with uneven rotor wear\u003c\/li\u003e\n\u003cli\u003eRestores braking performance compromised by rotor surface damage\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 28 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify that the five bolt holes and center hole align precisely with the vehicle hub. Use proper torque specifications for the lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-58039L rotor to meet or exceed OEM specifications for Acura MDX and TLX models.
