MPA Electrical BR55105G Disc Brake Rotor - Front

Coated Front Brake Rotor for OE-Style Stopping

The MPA Electrical BR55105G is a new, coated disc brake rotor built for front axle applications on select Cadillac and Pontiac models. It uses an OE-style vane design to support cooling and consistent braking performance, while the protective finish helps resist rust in demanding conditions.

Key Features

• Part number BR55105G
• Coated finish for added corrosion resistance
• OE-style vane design for efficient heat management
• Regular grade type for direct replacement service
• New condition rotor for front brake repair
• Compatible with 2005-2008 Cadillac STS front applications with 5 stud wheel and Performance Package
• Compatible with 2006-2007 Cadillac CTS front applications with Performance Suspension
• Compatible with 2004-2005 Pontiac Bonneville front applications

Detailed Description

Built for front brake service, the BR55105G rotor is engineered to restore smooth stopping performance without the noise, vibration, or fade associated with worn rotors. The coated surface helps protect the rotor from rust, and the vane design promotes airflow to help manage heat during repeated stops. This makes it a practical replacement for Cadillac STS, Cadillac CTS, and Pontiac Bonneville front brake repairs where OE-style fit and finish matter.

This part number, BR55105G, is a direct-fit style rotor for drivers looking to maintain factory braking feel on select Cadillac and Pontiac vehicles. BR55105G is a solid choice when replacing a worn front rotor on a 2006-2007 Cadillac CTS, a 2005-2008 Cadillac STS, or a 2004-2005 Pontiac Bonneville.

What It Helps Address

• Brake pulsation from rotor wear or uneven surfaces
• Noise caused by damaged or heat-affected rotors
• Reduced braking consistency during repeated stops
• Rust buildup on exposed rotor surfaces
• Loss of stopping performance on front brake service

Installation Notes and Tips

Verify front axle fitment before installation and match the vehicle configuration listed for your application. Inspect pads, calipers, and hub surfaces during rotor replacement, and clean the mounting area so the new rotor seats evenly. Follow the vehicle manufacturer’s service procedure for torque and bedding after installation.

Quality Assurance

MPA Electrical Quality-Built Black Series rotors use an OE-style vane layout and Q-Shield protective coating to support cooling and corrosion resistance in high-temperature, harsh-environment use. The BR55105G is a new, coated rotor built for consistent front brake service on select Cadillac and Pontiac applications.
