The rotor’s outside diameter measures 10.831 inches (275.100 mm), and the overall height is 2.039 inches (51.800 mm). It features a floating disc mounting style and a smooth surface type, which promotes even pad wear. The rotor includes five lug holes with a diameter of 0.559 inches (14.200 mm) and a mounting bolt hole circle diameter of 4.500 inches (114.300 mm). The center hole diameter is 2.799 inches (71.100 mm), accommodating proper hub fitment. Weighing 16 lbs (7.270 kgs), this rotor balances durability and performance without adding excessive unsprung weight.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Buick Aztek and Pontiac Rendezvous
• Addresses brake pulsation and vibration issues
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness for safe braking performance
• Eliminates uneven pad wear caused by damaged rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 1.118 inches (28.400 mm). Clean the rotor surface to remove any protective coatings or debris prior to mounting. Use proper torque specifications for the 5 lug bolts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
