Detailed Product Description

The DuraGo BR900464 disc brake rotor is constructed from full cast iron, providing a durable and heat-resistant braking surface. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. This reduces the risk of brake fade and maintains consistent braking performance under various driving conditions. The rotor's nominal thickness of 0.87 inches ensures a solid braking surface, while the discard thickness of 0.79 inches indicates when replacement is necessary to maintain safety and performance. With an outside diameter of 11.41 inches and a 5-bolt mounting pattern, this rotor is engineered to fit Mazda MX-5 Miata models precisely.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing vibration or noise during braking
• Upgrading from solid to vented rotors for improved heat dissipation
• Addressing rotor thickness below manufacturer specifications to restore braking efficiency
• Resolving uneven brake pad wear due to rotor surface irregularities
• Ensuring proper fitment for Mazda MX-5 Miata brake system maintenance

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface with brake cleaner to remove any protective coatings or debris
• Check mounting bolt hole alignment and torque bolts to manufacturer specifications
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a bed-in procedure after installation to optimize braking performance
