ATE Coated Single Pack Rotor Line

ATE Coated Single Pack Rotor products are part of ATE’s coated brake disc lineup, which draws on Continental Automotive Systems’ OE brake engineering background. The line focuses on premium brake materials and coating technology for corrosion protection and consistent service performance. SP22220 follows that approach with a coated vented rotor specification for rear brake replacement.

Detailed Description

SP22220 is a rear disc brake rotor for 2004-2009 Audi S4, 2005-2006 Audi A4, and 2005-2006 Audi A4 Quattro applications. It meets or exceeds North American OEM specifications for the listed fitments and uses a coated surface to help resist rust on exposed areas. The rotor’s 300 mm diameter, 22.00 mm thickness, and vented design align with the rear brake requirements for these Audi models. This part cross-references Brembo 09.A814.11 and MAHLE 54371 for the same application.

What It Helps Address

• Rear brake rotor wear on Audi S4 and Audi A4 platforms
• Brake pulsation caused by rotor surface irregularities
• Corrosion on exposed rotor surfaces
• Reduced braking consistency from worn vented rotors
• Replacement needs for 300 mm rear rotor applications

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and rear position before installation. Confirm pad condition, hub surface cleanliness, and caliper operation during service. For best results, replace rotors in pairs on the same axle and follow the vehicle manufacturer’s torque and bedding procedures.

Quality Assurance

ATE brake parts are produced to a higher standard than conventional aftermarket replacements, using engineering experience drawn from Continental Automotive Systems’ OE brake manufacturing background. SP22220 is built with first-quality materials and coated rotor technology for the specified Audi rear brake applications.
