Detailed Product Description

BR76025G is a rear brake rotor from MPA Electrical’s Black Series Coated Rotor line. The coated surface helps protect the rotor from rust in harsh conditions, while the OE-style vane layout supports cooling during repeated stops. This combination makes it a practical choice for drivers replacing worn rear rotors on Mercedes-Benz GLA250, CLA250, B250, B250e, B Electric Drive, and INFINITI QX30 applications.

The rotor uses a smooth surface type, solid rotor design, and coated finish on both the disc and hat. It is built as a standard replacement part for vehicles that require a rear rotor with 112.0 mm bolt circle diameter and 15.1 mm mounting bolt hole diameter. Part number BR76025G is also a useful reference when searching for a rear Mercedes-Benz CLA250 brake rotor or a rear INFINITI QX30 brake rotor.

What This Rotor Helps Address

• Brake noise caused by worn or uneven rear rotors
• Pedal vibration from rotor surface wear or thickness variation
• Reduced stopping consistency from heat buildup
• Rust and corrosion on exposed rotor surfaces
• Rear brake service needs on fitment-specific Mercedes-Benz and INFINITI models

Installation Notes and Tips

Confirm rear axle fitment, center hole diameter, bolt circle diameter, and rotor thickness before installation. Inspect pads, caliper hardware, and hub condition during brake service so the new rotor seats correctly and wears evenly. Clean the hub mounting surface before installing BR76025G to help reduce runout-related issues.

Quality Assurance

MPA Electrical Black Series rotors are built with OE-style vane geometry and Q-Shield coating for corrosion protection and stable braking performance. BR76025G is a new standard replacement rotor intended for direct brake service on the listed rear applications.
