Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The zinc black hat finish provides corrosion resistance, extending rotor life in various driving conditions. This product line is tailored for drivers seeking rotors that maintain consistent braking under stress while offering enhanced durability.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow between the rotor surfaces, helping to dissipate heat generated during braking. The drilled and slotted surface improves water and debris evacuation, reducing brake fade and maintaining pad contact. The rotor’s nominal thickness is 28 mm, with a discard thickness of 25 mm, ensuring safe replacement intervals. The zinc black finish on the hat section offers rust resistance, while the plain disc finish supports effective braking. The rotor is directional, meaning it must be installed in the correct orientation to maximize performance. It includes five bolt holes with a 110 mm bolt circle diameter, compatible with the specified Saab and Cadillac models.

Compatible Vehicles and Common Applications

• Replacement rotor for Saab 9-3 and 9-3X models
• Suitable for Cadillac BLS brake system upgrades or repairs
• Addresses issues such as brake fade during heavy use
• Helps reduce rotor warping caused by excessive heat
• Improves braking response in wet or debris-prone conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify the bolt pattern matches the vehicle’s hub (5 lug holes, 110 mm bolt circle). Check rotor thickness before installation to confirm it meets the nominal 28 mm specification and is above the discard thickness of 25 mm. Clean the rotor surface to remove any protective coatings or residues before mounting to ensure optimal pad contact.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant zinc black hat finish contributes to long-term corrosion protection. While specific warranty details are not provided, the rotor is designed for reliable service life when installed and maintained according to manufacturer guidelines.
