Stoptech 128.66064R Disc Brake Rotor - Front Right

StopTech Sport Cross-Drilled Front Right Rotor

The StopTech Sport Cross-Drilled Disc Brake Rotor is a direct replacement disc for factory brake systems and stock calipers. This front right rotor is built for 2006-2009 Chevrolet Trailblazer and 2008-2009 Saab 9-7x applications, with cross-drilled surfaces that support heat and brake dust dispersal.

Part number 128.66064R is a vented, floating-mount rotor with a coated hat finish and black e-coating for corrosion protection. The high-carbon metallurgy used in most applications supports quieter operation, improved crack resistance, and consistent braking performance in wet and dry conditions.

Product Details

StopTech Sport Cross-Drilled Disc Brake Rotors are engineered for drivers who want OE-style fitment with a performance-oriented surface design. The 128.66064R rotor uses cross-drilling to help manage heat buildup and brake dust while supporting more consistent braking response during repeated stops. For Chevrolet Trailblazer and Saab 9-7x front right brake service, this rotor provides a direct replacement solution that works with stock calipers.

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

Common Brake Issues This Rotor Can Address

• Brake fade during repeated stops
• Excess heat buildup at the rotor surface
• Brake dust accumulation on the braking surface
• Pad glazing that reduces braking response
• Corrosion on exposed rotor surfaces

Installation Notes and Tips

Confirm rotor dimensions, bolt pattern, and front right position before installation. Inspect pads, caliper condition, and hub surfaces during brake service to help ensure even contact and proper rotor seating. Because this rotor is a direct replacement for stock brake systems, it installs with factory-style components when the vehicle application matches.

Quality Assurance

StopTech designs Sport Cross-Drilled Rotors with corrosion-resistant coating and high-carbon metallurgy in most applications to support durability, quieter operation, and improved crack resistance. Part number 128.66064R is built for consistent performance in everyday driving and brake service applications.
