Detailed Product Description
The DuraGo BR901138 disc brake rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade. With a nominal thickness of 0.98 inches (25 mm) and a discard thickness of 0.91 inches (23 mm), this rotor maintains structural integrity throughout its service life. The rotor measures 12.6 inches (320 mm) in outside diameter and features five mounting bolt holes arranged on a 4.5 inch (114.3 mm) bolt circle diameter, ensuring precise fitment on compatible Mazda 3 vehicles. The non-directional brake surface allows for installation on either side without affecting performance.
Compatible Vehicles and Applications
This disc brake rotor is compatible with Mazda 3 models requiring a 12.6 inch rotor with five mounting bolts. It is designed to replace worn or damaged rotors and restore proper braking function.
- Eliminates brake pulsation caused by warped rotors
- Resolves excessive brake noise due to uneven rotor surfaces
- Addresses reduced braking efficiency from worn rotor thickness
- Prevents overheating and brake fade during extended use
Installation Notes and Tips
When installing the DuraGo BR901138 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Since this rotor is non-directional, it can be installed on either side of the vehicle. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking performance. Verify that the rotor thickness is above the discard limit of 0.91 inches (23 mm) before installation.
Quality Assurance and Warranty
DuraGo manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The full cast iron construction and vented design contribute to consistent braking performance and durability.
