Product Details

The DFC Rotors-Drilled and Slotted-Silver with DFC Drums line is engineered for drivers who want OE-style fitment with performance-focused rotor geometry. For applications such as Chevrolet Impala, Buick LeSabre, and Pontiac Catalina, the drilled holes and slots are used to manage heat, maintain pad contact, and keep the braking surface cleaner during repeated stops. The rotor castings are machined to tight tolerances, finished for even pad bedding, and inspected to confirm balance and OE specifications. Part number 7004-47003 is a direct catalog reference for these classic GM brake service applications.

Common Brake Issues Addressed

• Brake fade from heat buildup during repeated stops
• Reduced stopping response in wet weather
• Pad glazing caused by excess heat and debris
• Rotor vibration from imbalance or uneven machining
• Uneven brake feel on older full-size GM vehicles

Installation Notes

Verify rotor, drum, and shoe-kit compatibility before installation on your specific vehicle configuration. Clean all mating surfaces, inspect related brake components for wear, and follow proper bedding procedures after installation. This kit is listed for front and rear service on the vehicles shown above, including 1971-1976 Buick Riviera and 1971-1976 Chevrolet Caprice applications.
