Rear Coated Rotor for Porsche, Audi, and Volkswagen

MPA Electrical Black Series Coated Rotor BR78024G is a rear disc brake rotor built for OE-style replacement performance on select Porsche Cayenne, Audi Q7, and Volkswagen Touareg applications. It is engineered for smooth braking response, reduced noise, and corrosion protection in demanding driving conditions.

Key Features

• Black Series Coated Rotor with coated disc and coated hat finish
• OE-style vane design for efficient cooling and consistent stopping performance
• Q-Shield rust-resistant coating for added protection against corrosion
• Vented rotor construction with smooth surface type
• Standard replacement grade for direct brake service
• No ABS tone ring included and no bearings included
• Part number BR78024G for rear brake applications

Product Details

The MPA Electrical Black Series Coated Rotor line focuses on practical brake service needs: stable braking, heat management, and long-term surface protection. BR78024G uses an OE-style vane layout to help move heat away from the braking surface, while the coated finish helps resist rust exposure in harsh weather and high-temperature conditions. This rear rotor is a direct-fit option for 2005-2006 Porsche Cayenne rear, 2007-2015 Audi Q7 rear, 2008-2018 Porsche Cayenne rear, and 2008-2009 Volkswagen Touareg rear applications. If you are searching for a rear brake rotor for Porsche Cayenne, Audi Q7 rear rotor replacement, or Volkswagen Touareg rear disc brake service, BR78024G is built for those exact vehicle platforms.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Rotor Can Address

• Brake pulsation from worn rear rotors
• Noise caused by uneven or heat-affected rotor surfaces
• Reduced stopping consistency during repeated braking
• Rust buildup on exposed rotor surfaces
• Heat-related fade in demanding stop-and-go driving

Installation Notes and Tips

Confirm rotor thickness and hub dimensions before installation. BR78024G has a nominal thickness of 28.0 mm and a discard thickness of 26.0 mm, with a 5-lug pattern, 130.0 mm bolt circle diameter, and 85.0 mm center hole diameter. Inspect pads, calipers, and hub surfaces during brake service, and clean the mounting area before installing the new rear rotor.

Quality Assurance

MPA Electrical Black Series rotors use a coated finish and Q-Shield protection to help maintain surface integrity against rust while supporting consistent braking performance. The rotor is a new, standard replacement part built to OE-style specifications for the listed Porsche, Audi, and Volkswagen rear applications.
