Centric 120.80004 Disc Brake Rotor - Front or Rear

Centric Premium Disc Brake Rotor Overview

The Centric Premium Disc Brake Rotor, part number 120.80004, is built for drivers who need consistent braking performance and corrosion resistance in a replacement rotor. Its vented, smooth-surface design and electrocoated finish make it a practical choice for brake service on compatible applications, including select Chevrolet and GMC truck and SUV platforms.

Centric Premium Disc Brake Rotors are part of the Centric Premium Disc Brake Rotors line, which focuses on replacement rotors with durable surface protection for everyday driving and demanding weather exposure. The 120.80004 rotor uses an e-coating finish rather than a basic phosphate coating, helping protect the rotor surface after installation.

Detailed Description

This Centric brake rotor is engineered as a direct replacement disc brake rotor for compatible Chevrolet and GMC applications that use a 6-lug, behind-the-hub, vented front rotor configuration. The hat-shaped design, straight vane style, and precise dimensions support proper rotor fitment and stable braking feel when replacing worn or corroded original equipment parts. This part number 120.80004 is also cross-referenced to Monroe Shocks & Struts 172286 and 182286 for the same application.

Common Problems This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Surface rust on exposed rotor hats and braking surfaces
• Reduced braking consistency from worn or heat-affected rotors
• Noise and vibration associated with uneven rotor condition
• Replacement needs after rotor thickness reaches discard limits

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake issues, and inspect pads, calipers, and hardware condition during brake service. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation.

Quality Assurance

Centric’s electrocoating finish is designed to provide durable corrosion protection and withstand extended salt-water exposure testing. That finish helps preserve the rotor surface after installation, especially in wet or road-salt environments.
