Technical Details and Construction

The DuraGo BR900842 rotor features a full cast iron construction, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and helping to prevent brake fade during extended use. The rotor measures 12.4 inches in outside diameter and has a nominal thickness of 0.91 inches, ensuring compatibility with the braking system of the Cadillac SRX. This rotor is a drum-in-hat type, integrating the parking brake drum within the rotor assembly, which is common for this vehicle model. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Part Number

This disc brake rotor is specifically compatible with Cadillac SRX models, ensuring a precise fit and proper function. The part number BR900842 should be referenced when searching for replacement rotors for your Cadillac SRX to guarantee compatibility and performance.

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
• Resolving noise issues related to uneven rotor surfaces
• Upgrading to a vented rotor for improved heat management
• Ensuring proper fitment for drum-in-hat parking brake systems

Installation Notes and Tips

When installing the DuraGo BR900842 rotor on your Cadillac SRX, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the rotor thickness meets or exceeds the nominal thickness of 0.91 inches and is above the discard thickness of 0.85 inches. Use the 6 mounting bolt holes and confirm the bolt circle diameter of 4.72 inches matches your vehicle’s hub. Since this rotor does not include an ABS tone ring, ensure your vehicle’s ABS system is compatible or that the existing tone ring is retained.
