Product Details

Centric Premium Disc Brake Rotors are engineered with an electrocoating finish that provides long-lasting corrosion protection. Unlike basic phosphate coatings that mainly protect during storage and shipping, the e-coat finish is built to hold up after the rotor is installed and exposed to heat, moisture, and road spray. For drivers replacing worn front rotors on a Chevrolet Trailblazer, GMC Envoy, or Saab 9-7x, this rotor offers the dimensions and mounting layout needed for a direct-fit brake repair.

This part cross-references Raybestos Brakes 580023 and PowerStop AR8650 for the same application.

Common Brake Issues This Rotor Can Address

• Brake pulsation from rotor thickness variation
• Visible rotor rust on the hat or braking surface
• Noise caused by uneven rotor wear
• Reduced braking smoothness during stop-and-go driving
• Front brake service on high-mileage GM SUVs and crossover platforms

Installation Notes and Tips

Verify rotor diameter, center hole diameter, bolt pattern, and thickness before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake vibration. Always inspect pads, calipers, and hardware condition during rotor replacement, and follow the vehicle manufacturer’s torque specifications during wheel installation.
