Detailed Product Description

This Centric Premium Disc Brake Rotor (part number 120.40049) is specifically designed for Acura RL models, ensuring exact fitment and optimal braking performance. The rotor features a vented design that promotes better heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The floating mounting type allows for slight movement between the rotor and hub, which helps maintain proper alignment and reduces stress on the braking system.

The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, indicating the minimum thickness before replacement is necessary. Its overall diameter measures 300 mm (11.811 inches), with a smooth surface type that provides consistent contact with brake pads. The hat finish is coated to protect against corrosion, extending the rotor's service life. The rotor includes 5 bolt holes arranged in a 114.3 mm bolt circle diameter, matching the Acura RL's wheel hub specifications.

Applications and Problem Solving

• Replacement for worn or warped rotors on Acura RL vehicles
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Improves heat management to reduce brake fade during heavy use
• Restores proper rotor thickness for safe braking performance
• Prevents corrosion-related rotor damage with coated hat finish

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 28 mm and is above the discard thickness of 26 mm. The floating mounting type requires proper alignment during installation to maintain rotor movement and prevent binding. Use the 5 bolt holes with a 114.3 mm bolt circle diameter to secure the rotor to the hub. Clean the rotor surface before mounting brake pads to remove any protective coatings or debris.

Quality Assurance and Warranty

Centric Premium Disc Brake Rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The coated hat finish provides corrosion resistance to extend rotor life. While specific warranty details are not provided, Centric products typically undergo rigorous quality control to ensure durability and performance on Acura RL vehicles.
