Detailed Product Description

This Power Stop rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under demanding conditions. The rotor’s Geomet coating provides a rust-resistant surface, which is critical for maintaining rotor integrity and appearance over time, especially in environments prone to moisture and road salt exposure. With a nominal thickness of 1.10 inches (28.00 mm) and a discard thickness of 1.02 inches (26.00 mm), this rotor meets OEM specifications for safe and reliable braking performance. The overall height of 1.80 inches (46.00 mm) and outside diameter of 12.60 inches (321.10 mm) ensure proper fitment and compatibility with the front brake assemblies of the Buick Envision and Cadillac XT4.

About the Power Stop - Front Genuine Geomet Coated Rotor Line

The Power Stop - Front Genuine Geomet Coated Rotor line is designed to provide a balance of durability and corrosion resistance through the application of a Geomet coating. This coating reduces surface rust and extends the rotor’s service life without compromising braking performance. These rotors are engineered to meet or exceed OEM standards, making them suitable replacements for front disc brake rotors on compatible vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Buick Envision and Cadillac XT4
• Addresses brake noise caused by rust or uneven rotor surfaces
• Helps reduce brake fade by improving heat dissipation with vented design
• Prevents premature rotor corrosion in humid or salted road conditions
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor is installed on the front axle of Buick Envision or Cadillac XT4 models matching the specified dimensions. Verify the mounting bolt hole circle diameter of 120.00 mm and 5 lug holes for proper fitment. It is recommended to inspect brake pads and hardware during installation and replace if necessary. Clean the rotor surface before installation to remove any protective coating residue. Torque lug nuts to manufacturer specifications to avoid rotor warping.
