Product Details

The DFC Brake Rotor - Drilled and Slotted - Black is engineered as a direct-fit replacement rotor for select Chevrolet Blazer, Chevrolet S10, GMC Sonoma, GMC Jimmy, Oldsmobile Bravada, and Isuzu Hombre front left applications. The vented design supports heat management, while the drilled and slotted surface helps maintain consistent pad contact and braking response during repeated stops. The black zinc hat finish and rust resistant coating help preserve the rotor’s appearance in service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues It Can Address

• Brake pulsation caused by rotor wear or uneven surface condition
• Reduced braking consistency from heat buildup in the front brake system
• Visible rotor corrosion on the hat area
• Noise or vibration associated with worn front left rotors
• Service replacement needs for drilled and slotted rotor applications

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub center diameter before installation. This rotor is directional, so confirm left-side placement and orientation during service. Always inspect pads, caliper condition, and hub surfaces when replacing a front brake rotor on a Chevrolet Blazer, GMC Sonoma, or related application.

For best results, replace rotors in axle pairs when the opposite side also shows wear, and follow the vehicle manufacturer’s brake service procedures and torque specifications.
