Product Details

This DFC rotor is built around the fitment and dimensions needed for front axle brake replacement on select Volkswagen Jetta, Volkswagen Golf, Volkswagen Taos, Volkswagen Beetle, Volkswagen e-Golf, Volkswagen Golf SportWagen, Volkswagen Bora, Volkswagen Caddy, Audi A3, and Audi Q2 models. The 288 mm diameter, 65 mm center hole, and 49.8 mm overall height support OE-style fitment where specified, while the drilled and slotted face helps maintain pad bite and manage heat during repeated stops. The silver hat finish and rust resistant coating also help reduce visible corrosion on exposed surfaces.

Brand line note: the DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotors with a performance-oriented surface pattern and corrosion-resistant finish, making it a practical choice for drivers replacing worn front brake rotors on Audi A3, Audi Q2, and Volkswagen Jetta applications.

Common Problems This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking response from worn front rotors
• Surface corrosion on the rotor hat and exposed metal areas
• Noise or uneven pad contact from damaged braking surfaces
• Heat buildup during repeated stop-and-go driving

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and caliper configuration before installation. This front left rotor is directional, so orientation matters during service. Confirm vehicle-specific notes such as caliper type, rear brake setup, and production date where listed, especially on Volkswagen Jetta, Volkswagen Golf, and Volkswagen Caddy applications. Always inspect pads, calipers, and hub surfaces before installing a new rotor.

Quality Assurance

Built to match the listed dimensional specifications and fitment data for select Audi and Volkswagen vehicles. Part number 631-74028L should be matched to the exact application and position shown in the fitment list for proper installation.
