Product Details

ATE, the brake brand of Continental Automotive Systems, applies OE-level product and process engineering to aftermarket brake components. The ATE Coated Single Pack Rotor line focuses on coated brake discs that resist corrosion while maintaining the dimensional and material standards expected in demanding brake service. For Volvo XC90 rear brake applications, SP20122 provides a vented rotor design with a full cast build and a non-directional surface finish for straightforward pad bedding and service consistency. This rotor is a direct fit for 2014 Volvo XC90 rear, 2013 Volvo XC90 rear to chassis #633384, and 2003-2012 Volvo XC90 rear. This part cross-references Monroe Shocks & Struts (e.g., 32249) for the same application.

What This Rotor Helps Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor finish or surface condition
• Corrosion on exposed rotor surfaces
• Reduced braking consistency from rotor wear
• Service replacement needs for Volvo XC90 rear brake maintenance

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear position before installation. For 2013 Volvo XC90 applications, confirm the vehicle is built to chassis #633384 or later as specified in the fitment notes. Inspect pads, caliper hardware, and hub condition during rotor replacement to help ensure even contact and proper braking performance. Clean the coated surfaces only as needed during handling to avoid contaminating the braking surface.

Quality Assurance

ATE brake parts are produced with the engineering standards associated with Continental Automotive Systems and are made to meet or exceed North American original equipment specifications for the listed Volvo XC90 rear applications.
