Technical Description and Fitment

This disc brake rotor features a vented design with straight vanes to optimize airflow and heat dissipation during braking. The rotor’s nominal thickness of 1.035 inches (26.3 mm) ensures structural strength, while the discard thickness of 0.957 inches (24.3 mm) indicates when replacement is necessary. The rotor measures 10.248 inches (260.3 mm) in outside diameter and 2.012 inches (51.1 mm) in overall height, fitting vehicles with a 5-lug bolt pattern and a mounting bolt hole circle diameter of 4.528 inches (115 mm). The floating disc mounting design allows for slight movement to reduce stress and improve braking consistency.

This rotor is compatible with a variety of GM vehicles, including Buick models like Century and LeSabre, Cadillac models such as DeVille and Eldorado, Chevrolet Lumina APV, Oldsmobile Cutlass and Delta 88, Pontiac Bonneville and Grand Prix, and others like Allante, Seville, and Toronado.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Corrosion protection to prevent rust buildup on braking surfaces
• Improved heat dissipation to reduce brake fade under heavy use
• Restoring proper rotor thickness for safe braking performance
• Addressing uneven pad wear due to rotor surface irregularities

Installation Notes and Tips

• Ensure rotor thickness is within discard limits before installation
• Clean mounting surfaces to prevent rotor misalignment
• Use proper torque specifications on lug nuts to avoid rotor warping
• Check compatibility with ABS systems; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
