Detailed Product Description

The DuraGo BR901808 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for Mazda 3 vehicles. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup and helping to prevent brake fade during extended use. With a nominal thickness of 0.98 inches and a discard thickness of 0.91 inches, this rotor meets OEM specifications for thickness tolerances, ensuring safe and effective braking performance. The rotor’s outside diameter of 11.01 inches and 5-bolt mounting pattern with a 4.5 inch bolt circle diameter are engineered to match Mazda 3 brake assemblies precisely. This rotor does not include a rust-resistant coating or ABS tone ring, and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Compatible with Mazda 3 models requiring a 11.01 inch vented disc brake rotor
• Designed for vehicles with 5 mounting bolts and 4.5 inch bolt circle diameter
• Suitable for conventional brake systems without ABS tone ring integration

Common Issues Addressed by This Rotor

• Brake rotor warping or uneven wear causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Excessive heat buildup leading to brake fade on extended stops
• Noise or pulsation from damaged or out-of-spec rotors
• Replacement of OEM rotors to restore proper braking performance

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.91 inches) before installation
• Clean rotor surface and hub mounting area to prevent uneven contact
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check brake pads for wear and replace if necessary during rotor installation
• Perform a proper bed-in procedure after installation to optimize braking performance
