Details on the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide consistent braking performance under demanding conditions, making it suitable for trucks and SUVs such as the Cadillac Escalade and Chevrolet K1500 Suburban. The zinc silver hat finish and rust resistant coating help maintain rotor integrity over time.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking response and reducing the risk of brake fade. The rotor measures 295 mm in outside diameter and 66.6 mm in height, with a nominal thickness of 32.7 mm and a discard thickness of 30.86 mm, ensuring it meets OEM specifications for durability and performance. The zinc silver hat finish and rust resistant coating protect against corrosion, extending the rotor’s service life. The rotor is directional, meaning it must be installed in the correct orientation to optimize performance. It features six bolt holes with a 15.5 mm diameter and a bolt circle diameter of 139.7 mm, compatible with specific Cadillac, Chevrolet, and GMC models.

Compatible Vehicles and Common Applications

• Cadillac Escalade
• Chevrolet Blazer, K1500, K1500 Suburban, Suburban 1500, Tahoe
• GMC K2500, Yukon

This rotor is designed to address common braking issues such as:

• Brake fade caused by excessive heat buildup
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency in wet conditions
• Vibration or noise from warped or damaged rotors

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (6 holes, 15.5 mm diameter, 139.7 mm bolt circle) matches the vehicle hub. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 30.86 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed for lug nuts to avoid rotor warping.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-48008L rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and zinc silver hat finish contribute to long-term durability. Warranty details are provided by the manufacturer and should be confirmed at the time of purchase.
