Detailed Product Description

The DuraGo BR901812 disc brake rotor is engineered with a full cast construction using high-quality cast iron, ensuring durability and effective heat management during braking. This solid rotor features a nominal thickness of 0.35 inches (9 mm) and a discard thickness of 0.28 inches (7 mm), which helps maintain optimal braking performance and safety margins. The rotor's outside diameter measures 10.43 inches (264.8 mm), and it includes five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter, designed to fit securely on compatible Mazda 3 and CX-30 vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This rotor does not include an ABS tone ring and does not have rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Eliminating noise or vibration caused by uneven rotor surfaces
• Upgrading from drum brakes to disc brakes on compatible Mazda 3 or CX-30 models
• Restoring proper brake rotor dimensions for safe and reliable stopping power

Installation Notes and Tips

• Ensure rotor thickness is within nominal specifications before installation
• Clean rotor surface to remove any protective coatings or debris prior to mounting
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Check compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Inspect brake pads and calipers during rotor replacement for optimal brake system performance
