Product Line Details: Centric Premium Disc Brake Rotors

The Centric Premium Disc Brake Rotors line focuses on delivering rotors with precise manufacturing tolerances and enhanced durability. This product line features rotors with coated hats to reduce corrosion and vented designs to improve heat dissipation. The 120.44185 rotor benefits from these features, providing consistent braking performance and longevity for Lexus vehicles requiring a floating rotor design.

Technical Specifications and Features

This disc brake rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The floating mounting type allows slight movement between the rotor and hub, which can improve rotor alignment and reduce stress on the braking system. The rotor has a coated hat finish to protect against rust and corrosion, extending its service life. With a nominal thickness of 30 mm and a discard thickness of 27 mm, this rotor meets the necessary safety standards for replacement. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter ensures compatibility with specified Lexus models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Lexus GS and IS series vehicles
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves braking performance by restoring proper rotor thickness and surface smoothness
• Helps prevent brake fade during extended or heavy braking conditions
• Resolves corrosion-related rotor damage thanks to coated hat finish

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (27 mm) before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque lug nuts to manufacturer specifications for proper rotor alignment
• Check compatibility with ABS systems; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
