Brake Rotor Overview

This Dynamic Friction disc brake rotor is built for a specific front-left application and uses a slotted, cross-drilled surface for consistent braking performance. It is identified by part number 631-47012L and features a zinc silver hat finish with rust-resistant coating for added surface protection.

Key Features

• Slotted and cross-drilled rotor surface for improved pad contact management.
• Solid rotor construction with a plain disc finish.
• Zinc silver hat finish with rust-resistant coating.
• 4-lug pattern with 100 mm bolt circle and 56.9 mm center hole.
• Part number 631-47012L for accurate ordering and fitment lookup.

Detailed Description

The DFC Brake Rotor - Drilled and Slotted - Silver is engineered as a direct replacement-style brake rotor for older compact applications that use a 4 x 100 mm bolt pattern. Its directional slotted and drilled surface is paired with a solid rotor design, 246 mm outside diameter, and 11.05 mm nominal thickness to match the specified braking setup. The zinc silver hat finish and rust-resistant coating help protect exposed surfaces, while the plain disc finish keeps the braking face straightforward for service use. This rotor is listed for Fits 1978-1987 Chevrolet Chevette, front left and Fits 1981-1987 Pontiac T1000, front left. The part number 631-47012L is also useful when verifying the correct rotor for a Chevrolet Chevette or Pontiac T1000 brake service.

What It Is Used For

• Replacing a worn or scored front-left brake rotor.
• Restoring braking feel when rotor thickness is near discard limits.
• Addressing vibration or pulsation caused by rotor wear.
• Servicing a 4-lug, 100 mm bolt-pattern brake setup.

Installation Notes and Tips

Verify bolt circle diameter, center hole diameter, and rotor height before installation. Confirm the rotor matches the vehicle’s front-left position and inspect pads, caliper condition, and hub surfaces during service. Use the part number 631-47012L to confirm the correct application before assembly.

Quality Assurance

Dynamic Friction supplies this rotor with rust-resistant surface protection and a zinc silver hat finish for corrosion control on exposed areas. The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on application-specific brake components with fitment and dimensional accuracy in mind.
