Product Details and Specifications
The DuraGo BR901070-01 disc brake rotor is made from cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade. The rotor features a drum-in-hat construction, integrating the drum brake surface into the rotor hat for compatibility with vehicles equipped with rear drum brakes.
This rotor includes a rust resistant coating to help prevent corrosion, which is especially beneficial in regions with harsh weather or road salt exposure. The rotor measures 11.62 inches (295.1 mm) in outside diameter and has a nominal thickness of 0.75 inches (19 mm), with a discard thickness of 0.71 inches (18 mm), indicating when replacement is necessary. It has five mounting bolt holes with a bolt circle diameter of 4.5 inches (114.3 mm) and a center hole diameter of 2.8 inches (71.2 mm).
Compatible Vehicles and Applications
- Ford Ranger models requiring a 11.62-inch vented disc brake rotor
- Mazda B2300 trucks with drum-in-hat rear brake setup
- Mazda B4000 models needing a rust resistant, vented rotor
Common Issues Addressed by This Rotor
- Brake fade caused by excessive heat buildup during braking
- Corrosion and rust on rotor surfaces reducing braking efficiency
- Worn or warped rotors causing vibration or noise during braking
- Insufficient rotor thickness leading to decreased braking performance
- Compatibility issues with drum-in-hat rear brake systems
Installation Notes and Tips
Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness specification of 0.71 inches (18 mm) to maintain safe braking performance. This rotor is non-directional, allowing installation on either side of the vehicle. Confirm the mounting bolt pattern matches your vehicle’s specifications, specifically 5 bolt holes with a 4.5-inch bolt circle diameter. No ABS tone ring is included, so verify compatibility with your vehicle’s ABS system if applicable.
