The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black (part number 633-47038R) is engineered for Chevrolet Cobalt models requiring reliable braking performance. 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 Chevrolet Cobalt vehicles
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Black zinc-coated hat finish for corrosion resistance
• Nominal thickness of 20 mm with discard thickness at 18 mm
• Five bolt holes with 14.2 mm diameter and 110 mm bolt circle diameter
• Overall diameter of 292 mm and height of 62.7 mm

Detailed Product Features and Specifications

This DFC Brake Rotor from Dynamite Friction is designed with a vented rotor type that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor surface is both drilled and slotted, which assists in channeling away gases, dust, and water, improving braking consistency. The directional brake surface ensures optimal performance when installed correctly according to the rotation direction.

The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary to maintain safe braking. The hat section features a zinc black finish that provides rust resistance, extending the rotor’s service life. With five bolt holes sized at 14.2 mm diameter and a bolt circle diameter of 110 mm, this rotor fits securely on Chevrolet Cobalt models requiring this specification.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish on the hat. This product line is designed to offer enhanced heat management and durability for vehicles like the Chevrolet Cobalt, where consistent braking performance is critical. The drilled and slotted design helps maintain clean rotor surfaces and improves pad bite under various driving conditions.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent stopping power for Chevrolet Cobalt vehicles
• Addresses uneven pad wear by promoting better pad contact

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the wheel rotation. Verify that the bolt hole pattern matches the Chevrolet Cobalt specifications (5 bolts, 14.2 mm diameter, 110 mm bolt circle). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 20 mm. Replace the rotor if thickness is at or below the discard thickness of 18 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-47038R rotor to meet industry standards for durability and performance. The rust-resistant zinc black coating on the hat enhances corrosion protection. While specific warranty details are not provided, Dynamite Friction products typically adhere to quality control processes to ensure reliable fitment and function for Chevrolet Cobalt brake systems.
