Centric 125.39049 Disc Brake Rotor - Rear

Centric Rear Brake Rotor for Volvo

Centric Premium High Carbon Alloy Disc Brake Rotor 125.39049 is a rear vented rotor built for select Volvo applications that use a 320mm disc. It combines high-carbon metallurgy with a coated hat finish and smooth surface to support consistent braking performance on Volvo S60, S90, V60, V90, XC60, XC90, and V60 Cross Country models.

Key Features

• High carbon alloy construction helps reduce pad squeal with higher-friction European brake pad compounds
• Molybdenum and chromium alloy content improves resistance to cracking during repeated stop or higher-load use
• Increased carbon and chromium content improves oxidation resistance
• Vented rotor design supports heat management in rear braking applications
• Smooth surface and coated hat finish support clean installation and corrosion resistance at the hat area
• Floating mounting type with 5 bolt holes and 108mm bolt circle for confirmed Volvo fitments

Product Details

Centric’s Premium High Carbon Alloy Disc Brake Rotors line focuses on metallurgy and dimensional consistency for European braking systems. Part number 125.39049 uses a 320mm outside diameter, 20mm nominal thickness, 17.5mm discard thickness, 63.5mm center hole diameter, and straight vane construction. The rotor’s high-carbon alloy composition is intended to improve friction characteristics while helping the rotor better resist thermal stress and surface oxidation in demanding stop-and-go driving.

This part cross-references Four Seasons (e.g., 45915) for the same application.

What This Rotor Helps Address

• Brake squeal associated with high-friction pad compounds
• Rotor cracking from repeated braking heat cycles
• Reduced stopping consistency from worn or heat-stressed rear rotors
• Surface oxidation on exposed rotor areas
• Uneven braking feel caused by rotor wear beyond service limits

Before installation, verify rotor diameter, vented vs. solid configuration, hub bore, and mounting pattern against the vehicle’s brake package. For Volvo S60 rear brake rotor replacement, Volvo XC90 rear vented rotor service, or Volvo V60 Cross Country 320mm rear disc applications, confirm the brake system matches the listed notes and dimensions. Part number 125.39049 is specified for rear positions only.

Quality Assurance

Centric’s Premium High Carbon Alloy rotor line is engineered around advanced metallurgy, dimensional accuracy, and corrosion resistance for European braking systems. The coated hat finish and alloy composition support long-term service in rear brake applications where heat, noise, and oxidation control matter.
