About Centric Premium Disc Brake Rotors

The Centric Premium Disc Brake Rotors line focuses on delivering reliable, OE-quality replacement rotors. This product line emphasizes precise manufacturing standards and material consistency, providing rotors that meet or exceed original equipment specifications. The 120.44224 rotor exemplifies this approach with its full cast iron construction and vented design, suitable for maintaining braking efficiency and vehicle safety on Lexus IS and RC series models.

Detailed Product Description

This disc brake rotor is made from cast iron, a material known for its durability and heat resistance, which is critical for braking components. The vented vane style allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The drum-in-hat construction integrates a parking brake drum, eliminating the need for a separate drum component. With a mounting bolt hole quantity of five and a bolt circle diameter of 114.3 mm, this rotor fits securely on compatible Lexus vehicles. The nominal thickness of 0.709 inches ensures a solid braking surface, while the discard thickness of 0.650 inches indicates when replacement is necessary to maintain safety standards.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading from solid to vented rotors for improved heat dissipation
• Addressing brake noise or vibration issues related to rotor surface wear
• Restoring proper parking brake function with drum-in-hat design
• Ensuring compatibility with Lexus IS300, IS350, RC300, and RC350 models

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.709 inches. Replace rotors when thickness reaches the discard limit of 0.650 inches. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify the mounting bolt pattern matches the vehicle specifications, specifically 5 bolts on a 114.3 mm circle. Proper torque specifications should be followed to avoid rotor warping or uneven wear.
