DuraGo BR901966-01 Disc Brake Rotor - Rear

Durable Cast Iron Disc Brake Rotor for Jeep Grand Cherokee

The DuraGo BR901966-01 disc brake rotor is engineered to provide reliable braking performance for Jeep Grand Cherokee and Grand Cherokee L models. Constructed from full cast iron with a rust-resistant coating, this solid rotor offers consistent stopping power and durability under various driving conditions.

• Material: Full cast iron construction for strength and heat dissipation
• Nominal thickness: 0.55 inches (14 mm) ensuring long service life
• Discard thickness: 0.49 inches (12.4 mm) indicating when replacement is necessary
• Outside diameter: 12.8 inches (325 mm) compatible with specified Jeep models
• Mounting bolt hole quantity: 5 with 0.67 inch (17 mm) diameter holes
• Solid rotor design without slots or cross-drilling for standard braking needs
• Rust-resistant coating to reduce corrosion and extend rotor life
• Non-directional brake surface for flexible installation

Technical Details and Compatibility

This DuraGo disc brake rotor (part number BR901966-01) is designed specifically for Jeep Grand Cherokee and Grand Cherokee L vehicles. The rotor features a conventional solid design with an overall height of 1.61 inches (41 mm) and a center hole diameter of 2.83 inches (72 mm). The mounting bolt hole circle diameter measures 5 inches (127 mm), ensuring proper fitment on compatible brake hubs. The absence of an ABS tone ring means it is intended for vehicles without ABS sensor integration on the rotor.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust affecting braking efficiency
• Restoring proper rotor thickness to maintain safe braking distances
• Eliminating brake noise caused by uneven rotor surfaces
• Upgrading to a rust-resistant coated rotor for longer service intervals

Installation Notes and Tips

When installing the DuraGo BR901966-01 rotor on Jeep Grand Cherokee or Grand Cherokee L models, ensure the rotor surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 0.55 inches (14 mm). Use proper torque specifications for the 5 mounting bolts to avoid rotor warping. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction.
