Detailed Product Description
The DuraGo BR900506-01 rotor is constructed from full cast iron, providing a balance of durability and effective heat management during braking. Its vented design helps dissipate heat more efficiently than solid rotors, reducing the risk of brake fade under heavy use. The drum-in-hat configuration integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with rear drum parking brakes. This rotor features a rust-resistant coating to help prevent corrosion, which is especially beneficial in regions with wet or salty road conditions.
With precise dimensions including a 12.4 inch outside diameter and a nominal thickness of 0.91 inch, this rotor meets OEM specifications for Cadillac CTS and Chevrolet Camaro models. The 5-bolt mounting pattern with a 4.72 inch bolt circle diameter ensures proper fitment and secure installation. The non-directional brake surface allows for flexible rotor placement without concern for directional rotation.
Compatible Vehicles and Applications
- Cadillac CTS requiring a 12.4 inch vented disc brake rotor with drum-in-hat design
- Chevrolet Camaro models compatible with 5 bolt, 12.4 inch diameter rotors
- Vehicles needing a rust-resistant coated rotor for enhanced durability
- Applications where vented rotors improve braking performance and heat dissipation
- Rear brake systems utilizing drum-in-hat rotors for integrated parking brake function
Installation Notes and Tips
When installing the DuraGo BR900506-01 rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify the rotor thickness before installation; replace if below the discard thickness of 0.85 inch (21.5 mm). Use the correct torque specifications for the 5 mounting bolts to avoid 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 without concern for rotor orientation.
