Detailed Product Description

This Dynamite Friction disc brake rotor is designed for vented operation, which improves heat dissipation during braking. The directional drilled and slotted surface helps maintain clean contact between the brake pad and rotor, reducing the risk of glazing and improving wet weather braking. The rotor’s nominal thickness of 26 mm ensures structural integrity, while the discard thickness of 24 mm indicates when replacement is necessary to maintain safety. The zinc silver hat finish provides rust resistance, extending the rotor’s service life. With five bolt holes and a 114.3 mm bolt circle diameter, this rotor fits securely on the hub, ensuring proper alignment and performance.

Applications and Problem Solving

• Compatible with Ford Escape, Mazda Mariner, and Mercury Tribute models requiring a 302.5 mm rotor diameter
• Addresses brake fade caused by overheating through vented rotor design
• Reduces brake dust and debris buildup with drilled and slotted surface
• Prevents corrosion with rust-resistant zinc silver coating
• Maintains braking efficiency by indicating discard thickness for timely replacement

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the bolt hole pattern and center hole diameter match the vehicle hub for proper fitment. Use a torque wrench to tighten lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to optimize braking performance.
