Product Details

The Centric Premium Disc Brake Rotors product line focuses on corrosion control and consistent braking performance. This rotor uses an electrocoated finish rather than a basic phosphate coating, giving the exposed surfaces stronger protection against moisture and road salt after installation. For drivers servicing a 1997-1998 Volvo S90 or 1997-1998 Volvo V90, part number 120.39022 provides the correct rear rotor dimensions and mounting pattern for a direct replacement application.

This part cross-references Dorman - HELP 56996 and Raybestos Brakes 96773 for the same application.

Common Brake Issues It Can Address

• Rear brake rotor rust on the hat or non-friction surfaces
• Brake pulsation caused by worn rotor thickness
• Reduced braking consistency from scored or heat-worn rotors
• Noise from uneven rotor surfaces
• Corrosion-related service issues on older Volvo rear brake systems

Installation Notes and Tips

Verify rear axle fitment by matching the vehicle year, model, and rotor dimensions before installation. Inspect pads, caliper hardware, and hub condition at the same time so the new rotor seats evenly. Clean the hub mounting surface thoroughly to reduce runout concerns and follow the vehicle manufacturer’s torque specifications during assembly. Part number 120.39022 is a rear disc brake rotor with a floating/DIH mounting type and no ABS tone ring included.

Quality Assurance

Centric Premium Disc Brake Rotors are built with an electrocoating finish intended to provide lasting corrosion protection after service installation. The coated surface treatment is designed to outperform basic phosphate finishes in real-world exposure to heat and moisture.
