Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides additional rust resistance, making it suitable for vehicles exposed to moisture and road salt. This product line is designed to meet the specifications required by various GM luxury and performance models, ensuring compatibility and consistent braking performance.

Product Specifications and Features

This solid rotor features a plain disc finish with a directional surface type that includes both drilled holes and slots. The drilled holes help vent gases and reduce heat, while the slots assist in cleaning the brake pad surface and maintaining consistent friction. The rotor’s nominal thickness is 11 mm, with a discard thickness of 9 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver hat finish and rust-resistant coating protect against corrosion, extending the rotor’s service life. The rotor is designed with five bolt holes and lug holes, matching the bolt circle diameter of 115/118 mm, making it compatible with specific Buick, Cadillac, Oldsmobile, and Pontiac models.

Compatible Vehicles and Applications

• Buick Allante, LeSabre, Park Avenue
• Cadillac DeVille, Eldorado, Seville
• Oldsmobile Aurora, Regency, Toronado
• Pontiac Bonneville, Riviera

This rotor is intended for drivers seeking replacement disc brake rotors that maintain factory specifications and provide consistent braking performance on these GM vehicles.

Common Issues Addressed by This Rotor

• Brake rotor warping due to heat buildup
• Reduced braking efficiency from worn or glazed rotors
• Corrosion and rust damage on rotor surfaces
• Brake noise caused by uneven rotor surfaces
• Premature rotor wear from inadequate ventilation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9 mm before installation. Clean the hub surface and mounting points to prevent runout. Use proper torque specifications for the 5 lug bolts to avoid rotor distortion. The directional drilled and slotted surface must be installed following the rotation direction indicated on the rotor for optimal performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards. The rust-resistant zinc silver coating and corrosion protection extend rotor life.
