Technical Details and Construction

The BR900430 rotor features a full cast iron build, providing the necessary strength and thermal capacity for effective braking. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking cycles. The rotor measures 11.5 inches (292 mm) in outside diameter and has a nominal thickness of 0.79 inches (20 mm), with a discard thickness of 0.71 inches (18 mm) to indicate when replacement is necessary. The overall height is 1.63 inches (41.5 mm), and it includes five mounting bolt holes arranged on a 4.33 inch (110 mm) bolt circle diameter. This rotor does not include an ABS tone ring and features a conventional, non-directional brake surface suitable for the specified vehicle models.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with the following vehicles:

• Cadillac models requiring a 292 mm vented rotor
• Saab 9-3 and 9-3X models
• Saab BLS model

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration caused by warped rotors
• Reduced braking performance due to rotor wear below discard thickness
• Overheating and brake fade from insufficient heat dissipation
• Noise or uneven braking caused by damaged or uneven rotor surfaces
• Corrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

• Ensure rotor thickness is within nominal specifications before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check brake pads for wear and replace if necessary during rotor installation
• Perform a test drive to verify braking performance after installation
