Stoptech 128.62057R Disc Brake Rotor - Front Right

StopTech X-Drilled Front Right Rotor

The StopTech Sport Cross-Drilled Disc Brake Rotor, part number 128.62057R, is a direct replacement front right rotor for factory brake systems using stock calipers. It is built for drivers who want improved pedal response, cleaner heat management, and a more refined look behind the wheel.

Compatible With select Buick, Pontiac, and Oldsmobile front right applications, including Buick Century, Buick LeSabre, Pontiac Bonneville, and Pontiac Grand Prix. This rotor is also a fitment match for several other GM platforms listed below.

Key Features

• 1-piece direct replacement disc brake rotor for factory brake systems
• X-drilled surface helps disperse heat and brake dust
• Cross-drilled design helps reduce pad glazing and improve initial bite
• Black e-coating helps protect against corrosion
• High carbon metallurgy in most applications for quieter operation and improved crack resistance
• Vented rotor design with straight vane construction
• Coated hat finish for added durability and appearance
• Part number 128.62057R for front right fitment verification

Product Details

StopTech Sport Cross-Drilled Disc Brake Rotors are engineered as OE-style replacements for stock calipers while adding performance-focused features. The 278 mm outside diameter, 70.7 mm center hole diameter, 5-lug bolt pattern, and vented construction support proper fitment on the listed vehicles. The drilled surface is intended to help move heat and dust away from the braking surface, which can improve wet and dry braking consistency during everyday driving. Part number 128.62057R is a useful reference when matching the correct front right rotor for GM applications such as Buick Regal, Oldsmobile Silhouette, and Pontiac Montana.

What This Rotor Helps Address

• Brake fade from heat buildup during repeated stops
• Excess brake dust accumulation on the rotor face
• Pad glazing that can reduce braking response
• Corrosion on exposed rotor surfaces
• Uneven braking feel caused by worn or damaged factory rotors

Installation Notes

Install on the front right position only for the listed applications. Verify rotor dimensions, wheel clearance, and brake system configuration before installation. One fitment note applies to 2000-2005 Buick LeSabre with 15-inch wheels, and 1998-1999 Oldsmobile Intrigue with JB9 standard brakes. Always inspect pads, caliper condition, and hub surfaces during rotor replacement to help ensure proper braking performance.

Quality Assurance

StopTech uses black e-coating for corrosion protection and high carbon metallurgy in most applications to improve durability, reduce noise, and increase crack resistance. This rotor is built as a direct replacement for factory brake systems and stock calipers, with fitment confirmed for 1997-2005 Buick Century, 1997-2004 Buick Regal, 1998-2005 Pontiac Bonneville, and other listed GM vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
