Dynamite Friction 631-27052R Disc Brake Rotor - Rear Right

Overview of the DFC Brake Rotor - Drilled and Slotted - Silver

The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver offers reliable braking performance for select Volvo models. Designed with a vented, directional surface, this rotor balances heat dissipation and consistent stopping power for vehicles like the Volvo S60 and XC90.

• Nominal thickness: 20 mm for durability and consistent wear
• Vented disc type enhances cooling during heavy braking
• Directional slotted and drilled surface improves brake pad bite and debris removal
• Zinc silver hat finish with rust-resistant coating for corrosion protection
• Precision bolt hole diameter of 15.7 mm with 5 lug holes on a 108 mm bolt circle diameter
• Outside diameter of 320 mm and overall height of 43.1 mm for exact fitment

Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver by Dynamite Friction is engineered to meet the braking demands of Volvo vehicles including the S60, S90, V60, V60 Cross Country, V90, V90 Cross Country, XC60, and XC90. This rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The directional slotted and drilled surface pattern helps evacuate gases, dust, and water from the braking surface, maintaining consistent friction and improving overall brake response.

The rotor’s hat is finished in zinc silver and coated with a rust-resistant layer to protect against corrosion, extending the rotor’s service life. With a nominal thickness of 20 mm and precise bolt hole dimensions, this rotor ensures a secure and accurate fit. The part number 631-27052R corresponds specifically to this rotor, making it a direct replacement for compatible Volvo models.

Applications and Problem Solving

• Reduces brake fade caused by overheating during aggressive driving or towing
• Improves braking performance in wet or dusty conditions through slotted and drilled design
• Prevents rust and corrosion on the rotor surface for longer service intervals
• Restores proper rotor thickness and surface condition for smooth braking
• Ensures compatibility with Volvo S60, XC90, and other specified models for reliable fitment

Installation Notes and Tips

When installing the 631-27052R rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the bolt hole alignment with the vehicle’s hub using the 5-lug, 108 mm bolt circle diameter pattern. It is recommended to replace brake pads simultaneously to optimize braking performance and avoid uneven wear. Proper torque specifications should be followed to secure the rotor and maintain safety.

Quality Assurance

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet industry standards for durability and performance.
