Detailed Product Description

The DuraGo BR900830 disc brake rotor is constructed from full cast iron, providing a durable and heat-resistant braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat more effectively during braking. This reduces the risk of brake fade and maintains consistent stopping power. The rotor features a drum-in-hat design, integrating a parking brake drum within the rotor assembly, which is compatible with the parking brake system on Cadillac CTS and STS vehicles.

With an outside diameter of 14.37 inches (365 mm) and a nominal thickness of 1.1 inches (28 mm), this rotor meets the precise specifications required for proper fitment and performance. The mounting bolt pattern includes 6 holes spaced on a 4.53 inch (115 mm) bolt circle diameter, ensuring secure attachment to the wheel hub. The non-directional brake surface allows for installation on either side of the vehicle without affecting performance.

Compatible Vehicles and Applications

• Cadillac CTS (specific model years should be verified for compatibility)
• Cadillac STS (specific model years should be verified for compatibility)

This rotor is designed to replace worn or damaged rotors on these Cadillac 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 braking
• Parking brake malfunction related to rotor drum wear

Installation Notes and Tips

When installing the DuraGo BR900830 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 1.02 inches (26 mm). Use proper torque specifications for the mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
