Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver features a vented design that improves airflow to reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The rotor measures 303 mm in outside diameter and 51.9 mm in overall height, with a nominal thickness of 32.3 mm and a discard thickness of 30.7 mm, ensuring durability and longevity within specified wear limits.

The rotor’s hat is coated with a zinc silver finish to resist rust and corrosion, extending service life in various driving conditions. It includes five bolt holes with a diameter of 16.2 mm and a bolt circle diameter of 118 mm, matching the lug pattern on compatible vehicles. The directional surface type is designed to optimize braking performance by channeling heat and debris away from the rotor surface.

Compatible Vehicles and Applications

This rotor is compatible with a range of GM vehicles, including Buick Aurora, LeSabre, and Park Avenue; Cadillac DeVille, Eldorado, Seville, and Seville; Chevrolet Camaro, Impala, and Monte Carlo; Oldsmobile Intrigue and Regency; and Pontiac Bonneville, Firebird, and Riviera. The part number 631-45008L ensures precise fitment for these models, providing a direct replacement for worn or damaged rotors.

• Improves braking performance on Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac models
• Addresses brake fade caused by overheating
• Reduces brake dust buildup and rotor glazing
• Helps prevent rust and corrosion on rotor surfaces
• Restores proper rotor thickness and surface condition

Installation Notes and Tips

When installing the 631-45008L rotor, ensure the rotor surface is clean and free of oil or debris before mounting. Verify the rotor thickness is above the discard thickness of 30.7 mm to maintain safety and performance. Use proper torque specifications for the 5 lug bolts (16.2 mm diameter) and confirm the rotor is installed with the directional surface facing the correct rotation direction. It is recommended to replace brake pads simultaneously to ensure optimal braking efficiency.
