Product Line Details: Centric Premium Disc Brake Rotors

The Centric Premium Disc Brake Rotors line focuses on delivering rotors that meet or exceed OEM specifications. This product line emphasizes precision manufacturing, corrosion-resistant coatings, and design features such as vented and floating rotors to enhance braking efficiency and rotor longevity. The 120.44184 rotor is part of this line, providing a balance of performance and durability for Lexus vehicles requiring reliable disc brake components.

Technical Specifications and Features

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade. The floating mounting type allows slight movement between the rotor and hub, which helps maintain proper alignment and reduces uneven wear. The rotor has a smooth surface type, suitable for consistent pad contact and braking performance. The coated hat finish protects against rust and corrosion, extending the rotor's service life.

With a bolt hole quantity of 5 and a mounting bolt hole circle diameter of 114.3 mm, this rotor fits securely on compatible Lexus models. The outside diameter measures 334 mm, and the nominal thickness is 30 mm, with a discard thickness of 27 mm, indicating when the rotor should be replaced to maintain safe braking performance.

Compatible Lexus Models and Applications

• Lexus GS300, GS350, GS450h
• Lexus IS200t, IS300, IS350
• Lexus RC200t, RC300, RC350

This rotor is designed specifically for these Lexus models, ensuring proper fitment and braking function when replacing worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear reducing braking efficiency
• Corrosion and rust on rotor surfaces
• Uneven rotor thickness leading to brake noise
• Overheating and brake fade under heavy use

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27 mm before installation. Clean the hub surface and mounting area to prevent misalignment. Use proper torque specifications for the 5 mounting bolts on the 114.3 mm bolt circle. Since this rotor does not include bearings or ABS tone rings, verify compatibility with your vehicle’s existing components. The floating mounting type requires careful alignment during installation to maintain proper rotor movement.
