Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps prevent brake fade during extended use. The directional slotted and drilled surface improves water and debris evacuation, maintaining effective braking in wet or harsh environments. The rotor’s nominal thickness is 23 mm, with a discard thickness of 21.5 mm, indicating when replacement is necessary to maintain safety. The zinc black hat finish and rust-resistant coating protect against corrosion, preserving the rotor’s structural integrity over time.

Applications and Problem Solving

• Restores braking performance on Cadillac SRX and Saab 9-4X vehicles
• Reduces brake fade caused by overheating during heavy braking
• Improves water and debris clearance for consistent stopping power in wet conditions
• Prevents rust and corrosion on rotor surfaces for longer service life
• Maintains proper rotor thickness to ensure safe braking operation

Installation Notes and Tips

Ensure the rotor is compatible with your vehicle’s make and model before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications for the 6 bolt holes (16.06 mm diameter) to secure the rotor firmly. Inspect brake pads and calipers during installation to confirm even wear and proper function.
