Product Details

Centric’s C-TEK Standard Disc Brake Rotors are positioned for routine brake repair where dependable stopping performance and practical value matter.

What It Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotors at or near discard thickness
• Noise and vibration associated with brake rotor wear
• Service replacement needs for a solid rear or front rotor application
• Fitment issues when the vehicle requires a 4-bolt, behind-the-hub rotor design

Installation Notes and Tips

Verify rotor dimensions, bolt circle diameter, center hole diameter, and mounting style before installation. Clean the hub mounting surface thoroughly so the rotor seats flat behind the hub. Inspect brake pads, caliper hardware, and wheel bearings during service, and measure rotor thickness after installation to confirm it remains above discard specification. For Honda Civic and Toyota Corolla brake jobs, confirm the exact year, position, and brake package before ordering part number 121.10004.
