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 and quality materials, providing vented rotors with coated hats to reduce corrosion and extend service life. The 120.62057 rotor is part of this line, ensuring compatibility and performance for specific Buick, Oldsmobile, and Pontiac vehicles.

Technical Description and Specifications

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 for slight movement to accommodate thermal expansion and contraction, enhancing rotor longevity. The coated hat finish protects the rotor hub from rust and corrosion, which is critical for maintaining proper fitment and ease of installation. With a nominal thickness of 1.272 inches and a discard thickness of 1.223 inches, this rotor maintains safe braking performance within specified wear limits. The rotor’s 10.945-inch outside diameter and 118 mm bolt circle diameter with five lug holes ensure precise fitment on compatible vehicles.

Compatible Vehicles and Applications

• Buick models including Century, LeSabre, Regal, and Park Avenue
• Oldsmobile models such as 88 and LSS
• Pontiac models including Bonneville, Grand Prix, and Montana
• Other compatible GM vehicles like Silhouette and Trans Sport

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking efficiency
• Corrosion on rotor hats affecting mounting and longevity
• Overheating and brake fade under heavy use
• Uneven rotor surface causing brake noise or pulsation

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface and hub to prevent runout
