With a 5-lug hole pattern and exact center hole and bolt circle diameters, this rotor ensures proper fitment and secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Eliminating noise or vibration from uneven rotor surfaces
• Upgrading to a vented rotor for better heat management in daily driving
• Ensuring proper fitment on Volvo 850, 960, C70, S70, S90, V70, and V90 models

Installation Notes and Tips

When installing the Centric C-TEK Standard Disc Brake Rotor 121.39019, ensure the rotor surface is clean and free of any protective coatings before mounting.
