This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Cadillac CTS vehicles
• Directional slotted and drilled surface for improved brake pad bite and heat management
• Vented rotor design to reduce brake fade
• Rust-resistant zinc silver hat finish for corrosion protection
• Nominal thickness of 30 mm with discard thickness at 28.5 mm
• Five bolt holes with 16.6 mm diameter and 120 mm bolt circle diameter
• Overall diameter of 316 mm and height of 51 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which assists in removing brake dust, gases, and water from the contact area, improving braking consistency and reducing the risk of brake fade. The directional brake surface ensures optimal performance when installed in the correct orientation.

The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.5 mm, indicating the minimum safe thickness before replacement is necessary. The zinc silver coating on the rotor hat provides rust resistance, extending the rotor’s service life. With five bolt holes sized at 16.6 mm diameter and a bolt circle diameter of 120 mm, this rotor is designed to fit securely on the Cadillac CTS hub assembly. The overall diameter of 316 mm and height of 51 mm are engineered to match factory specifications for proper fitment and performance.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced surface treatments to improve braking efficiency and rotor longevity. This product line combines drilled holes and slots on the rotor surface to optimize heat dissipation and debris removal, making it suitable for drivers who demand consistent braking performance in various driving conditions. The silver zinc coating on the rotor hat adds corrosion resistance, which is particularly beneficial for vehicles exposed to moisture and road salts.

Applications and Problem Solving

• Reduces brake fade during heavy or repeated braking
• Improves brake pad cleaning and gas venting for consistent stopping power
• Prevents rust and corrosion on rotor hats to extend component life
• Maintains proper braking performance for Cadillac CTS vehicles
• Ensures safe rotor thickness with clear discard limits

Installation Notes and Tips

When installing the 631-46025L rotor on a Cadillac CTS, ensure the directional surface is oriented correctly according to the vehicle’s rotation direction. Verify that the rotor thickness is above the discard thickness of 28.5 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications on the five lug bolts with 16.6 mm diameter to secure the rotor firmly. It is recommended to inspect brake pads and other braking components during installation for optimal system performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-46025L rotor to meet or exceed OEM specifications for fit, form, and function on Cadillac CTS models. The rust-resistant zinc silver coating and vented rotor design contribute to durability and consistent braking performance. Warranty details are subject to the manufacturer’s terms and should be verified at the time of purchase.
