Centric 120.86003 Disc Brake Rotor - Front or Rear

Centric Premium Disc Brake Rotor Overview

The Centric Premium Disc Brake Rotor, part number 120.86003, is built for heavy-duty braking applications where corrosion resistance and consistent rotor performance matter. Its vented, smooth-surface design and electrocoated finish make it a practical choice for drivers maintaining commercial or specialty vehicles that use a 10-bolt, behind-the-hub rotor layout.

Key Features

• Centric Premium Disc Brake Rotors line with electrocoated corrosion protection
• Vented rotor design for heat management during repeated braking
• Smooth surface type for a clean braking interface
• Behind-the-hub mounting configuration
• 10 bolt holes with a 249.94 mm bolt circle diameter
• Outside diameter: 430.00 mm; overall height: 138.4 mm
• Nominal thickness: 45.0 mm; discard thickness: 37.0 mm
• Center hole diameter: 219.9 mm
• Part number 120.86003 for catalog matching and cross-reference lookup

Detailed Description

Centric Premium Disc Brake Rotors are engineered with an electrocoating finish that helps protect the rotor from rust after installation, especially in wet or salted-road environments. Unlike basic phosphate coatings that mainly protect during storage and shipping, this finish is built to remain effective after the rotor is in service. The vented pillar-vane construction supports airflow through the rotor, while the large 430 mm outside diameter and 45 mm nominal thickness reflect a rotor intended for demanding braking systems. If you are sourcing a replacement rotor for a commercial truck, bus, or other heavy-duty platform, 120.86003 provides the dimensional details needed for accurate catalog matching.

This part cross-references Carlson 41305 for the same application.

What This Rotor Helps Address

• Brake rotor corrosion after exposure to moisture, road salt, and humidity
• Brake pulsation caused by worn or out-of-spec rotor surfaces
• Heat buildup during repeated stops in heavy-duty service
• Fitment issues on vehicles requiring a 10-bolt, behind-the-hub vented rotor
• Replacement needs for commercial braking systems using the 120.86003 specification

Installation Notes and Tips

Verify outside diameter, center hole diameter, bolt circle, bolt hole count, and overall height before installation. This rotor uses a behind-the-hub mounting style and a vented pillar-vane design, so matching the original brake package is important. Clean the hub mounting surface thoroughly and inspect related brake components for wear before installing the new rotor. For fitment-based searches, this rotor is commonly referenced for heavy-duty brake service on compatible commercial applications such as Freightliner and International platforms.

Quality Assurance

Centric Premium Disc Brake Rotors use an electrocoated finish for long-lasting corrosion protection, with resistance described by the manufacturer as suitable for extended salt-water exposure. The Centric Premium Disc Brake Rotors line is positioned for dependable replacement performance where rotor durability and finish quality are important.
