Dynamic Friction 631-74037L Disc Brake Rotor - Front Left

Brake Rotor for Volkswagen Applications

This Dynamic Friction disc brake rotor is built for specific Volkswagen Vanagon and Volkswagen Transporter fitments with front left placement and caliper-specific notes. The DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-74037L, combines a directional braking surface with corrosion-resistant finishing for service-focused replacement use.

Key Features

• Slotted and drilled surface for consistent pad contact and heat management.
• Directional brake surface for application-specific rotation.
• Rust-resistant coating with zinc silver hat finish.
• Solid rotor construction with 5-lug, 112 mm bolt circle fitment.
• Part number 631-74037L for catalog matching and ordering.

Detailed Description

The DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-74037L, is a solid disc brake rotor with an 278 mm outside diameter, 118.7 mm overall height, and 60 mm center hole diameter. Its plain disc finish, slotted X drilled surface, and directional braking face are paired with a rust-resistant coating and zinc silver hat finish to support long-term appearance and serviceability. Compatible With Volkswagen Vanagon and Volkswagen Transporter front left brake applications listed in the fitment data, including caliper-specific configurations.

This rotor is intended for Volkswagen Vanagon and Volkswagen Transporter brake service where the original rotor specification calls for a 5-lug, 112 mm bolt circle, solid rotor design, and directional surface pattern. The part number 631-74037L should be matched carefully to the vehicle’s brake setup, especially on 1979 Transporter applications with production-date and caliper notes.

Common Issues This Part Can Address

• Brake pulsation caused by worn or uneven rotor surfaces.
• Reduced braking consistency from heat-affected rotor faces.
• Surface corrosion on exposed rotor and hat areas.
• Rotor replacement needs on caliper-specific Volkswagen front brake setups.

Installation Notes and Tips

Verify the vehicle’s year, model, production date, caliper type, and front left position before ordering. Confirm rotor dimensions, bolt circle, and center hole diameter against the existing brake assembly. Because the fitment includes Girling and ATE brake configurations, matching the brake hardware specification is essential for correct installation.

Quality Assurance

Dynamic Friction supplies this rotor under the DFC Brake Rotor line, which emphasizes application-specific brake components with corrosion-resistant finishing and directional surface design. Part number 631-74037L is cataloged for the listed Volkswagen fitments and should be selected by exact brake configuration.
