The 121.42064 rotor is part of this line, featuring vented construction to help reduce heat buildup and maintain braking performance over time.

Technical Details and Specifications

This disc brake rotor is vented with straight vanes, which enhances airflow and cooling during braking. The rotor’s nominal thickness is 0.866 inches (22.000 mm), with a discard thickness of 0.787 inches (20.000 mm), indicating when replacement is necessary to maintain safety. The overall height of 1.937 inches (49.200 mm) and outside diameter of 10.118 inches (257.000 mm) ensure proper fitment on Nissan 240SX models. The rotor mounts using a floating disc mounting system with five lug holes, each 0.504 inches (12.800 mm) in diameter, arranged on a 4.500 inch (114.300 mm) bolt circle diameter. The smooth surface type promotes even pad wear and consistent braking feel.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading from solid to vented rotors for improved heat dissipation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving uneven brake pad wear linked to rotor surface irregularities
• Maintaining proper fitment and safety on Nissan 240SX brake systems

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness specification of 0.787 inches (20.000 mm). Use proper torque specifications for mounting bolts on the 4.500 inch (114.300 mm) bolt circle. Since this rotor does not include bearings or an ABS tone ring, confirm compatibility with your vehicle’s existing components. Proper bedding of new rotors and pads is recommended to optimize braking performance.
