Overview

This Dynamic Friction disc brake rotor is a fitment-specific replacement for classic full-size GM applications that use a front right rotor configuration. The DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-47006R, combines a vented design with a directional slotted-and-drilled surface for consistent braking performance.

Compatible With 1977-1978 Pontiac Grand Safari and 1977 Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac models listed below, this rotor is built around the specified bolt pattern, center bore, and height dimensions for accurate fitment. The 631-47006R part number is also useful when verifying the correct replacement before ordering.

Key Features

  • Vented rotor construction for improved heat management.
  • Slotted and drilled surface type with a directional braking face.
  • Zinc silver hat finish with rust-resistant coating.
  • 5-lug pattern with 127 mm bolt circle and 77.7 mm center hole.
  • Plain disc finish with OE-style dimensional specifications.

Detailed Description

The DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-47006R, is engineered for vehicles that require a front right disc brake rotor with the listed dimensions and mounting pattern. Its vented construction, directional surface, and drilled-and-slotted face are intended to support stable braking characteristics while the zinc silver hat finish and rust-resistant coating help protect exposed surfaces from corrosion. This rotor is a practical choice for restoring braking service on applications such as Pontiac Grand Safari, Buick Riviera, and Chevrolet Caprice.

For buyers searching by fitment, this rotor matches the specified classic GM applications rather than a universal size. The 631-47006R designation should be matched against the vehicle listing and brake configuration notes to confirm the correct application before installation.

What It Helps Address

  • Brake rotor wear that affects stopping consistency.
  • Surface corrosion on the rotor hat and exposed areas.
  • Heat buildup during repeated braking.
  • Brake pulsation caused by an out-of-spec rotor.
  • Fitment issues when replacing a front right rotor on listed GM vehicles.

Installation Notes and Tips

Verify the vehicle’s brake configuration, wheel bolt pattern, center bore, and rotor height before installation. This rotor is listed for front right applications only, and several fitments include drum-size or brake-package notes that should be checked carefully. Match the part number 631-47006R to the vehicle listing to confirm the correct application for Buick, Cadillac, Chevrolet, Oldsmobile, or Pontiac models.

Quality Assurance

Dynamic Friction supplies brake components for replacement use with published dimensional and finish specifications. The zinc silver hat finish and rust-resistant coating add surface protection, while the vented, directional drilled-and-slotted design supports consistent brake service on the listed applications.
