Product Details

Power Stop’s drilled and slotted rotor line focuses on cooling and surface control under demanding braking conditions. The cross-drilled pattern helps move heat away from the braking surface, while the rounded slots sweep away gases, dust, and moisture to maintain a cleaner contact patch. The zinc-plated finish adds corrosion resistance for long-term appearance and service life. This rear rotor application is listed with a 10.40-inch outside diameter, 5-lug mounting pattern, and solid rotor construction.

Common Brake Issues It Can Address

• Brake fade from repeated stops or higher heat buildup
• Rotor surface rust on exposed braking components
• Dust, gas, or moisture buildup on the rotor face

• Need for a direct replacement during rear brake service

Installation Notes and Tips

Verify rear fitment by year, model, and any listed notes before installation. Confirm rotor diameter, bolt circle, and thickness against the existing part to ensure the correct application. Clean the hub mounting surface before installing the new rotor to help reduce runout concerns and support even brake contact.
