The vented design in this product line helps reduce brake fade by allowing better airflow during operation.

Technical Specifications and Features

The 580137R rotor is a vented, conventional disc brake rotor designed to fit vehicles requiring a 10.080 inch outside diameter and a 1.840 inch overall height. It features four mounting bolt holes arranged on a 3.937 inch bolt circle diameter, matching the OEM fitment for the specified Chevrolet, Pontiac, and Saturn models. The nominal thickness of 0.945 inches ensures optimal braking surface, while the discard thickness of 0.866 inches indicates when replacement is necessary to maintain safe braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Improving heat dissipation to prevent brake fade during extended use
• Restoring proper rotor dimensions for vehicles with Chevrolet Cobalt, Pontiac G5, or Saturn Ion brake systems
• Ensuring compatibility with vehicles requiring a vented, conventional rotor design

Installation Notes and Tips

Before installation, verify rotor dimensions against the vehicle’s OEM specifications. Ensure the mounting surface is clean and free of debris to prevent rotor runout. Use proper torque settings on the four mounting bolts to secure the rotor evenly. It is recommended to replace brake pads simultaneously to maintain balanced braking performance. Check rotor thickness regularly and replace when reaching the discard thickness of 0.866 inches.
