Detailed Product Description

The DuraGo BR900690 disc brake rotor is constructed from full cast iron, providing the necessary strength and thermal capacity for heavy-duty braking applications. Its vented design allows air to flow between the rotor surfaces, helping to reduce heat buildup during braking and maintain consistent stopping power. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles that use drum parking brakes, such as the Ford E-350 Econoline and E-350 Super Duty.

This rotor features a nominal thickness of 1.42 inches (36 mm) and a discard thickness of 1.34 inches (34 mm), ensuring a clear service limit for safe operation. The 8 mounting bolt holes with a 5.71-inch (145 mm) bolt circle diameter provide secure attachment to the hub assembly. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Ford E-350 Econoline
• Ford E-350 Super Duty

This rotor is designed to replace worn or damaged rotors on these specific Ford models, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Excessive brake noise from uneven rotor surfaces
• Overheating and brake fade during heavy use
• Parking brake malfunction related to rotor drum wear

Installation Notes and Tips

When installing the DuraGo BR900690 rotor, ensure the rotor surface is clean and free of rust or debris. Verify that the rotor thickness is above the discard limit before installation. Use proper torque specifications for the 8 mounting bolts to avoid rotor warping. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. The non-directional design allows installation on either side of the vehicle.

Quality Assurance and Warranty

DuraGo manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The cast iron construction and vented design contribute to consistent braking performance under demanding conditions. While no rust resistant coating is applied, proper maintenance can help extend rotor life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
