Black Series Rotor Line Details

MPA Electrical Black Series Coated Rotor products are built for drivers who want a direct replacement rotor with added surface protection. The Q-Shield coating is formulated to withstand high temperatures while helping guard against corrosion, making BR77105G a practical choice for rear brake service on the Mazda CX-5.

Detailed Description

BR77105G is a coated disc brake rotor for the rear axle of the Mazda CX-5. The rotor’s vane design supports airflow through the braking surface to help manage heat during repeated stops, while the coated finish adds protection against rust in harsh weather and road-salt exposure. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Rotor Helps Address

• Rear brake pulsation from worn or uneven rotor surfaces
• Brake noise caused by rotor wear or surface corrosion
• Reduced stopping consistency during repeated braking
• Rust buildup on exposed rotor surfaces
• Heat-related fade during stop-and-go driving

Installation Notes and Tips

Fits 2019 Mazda CX-5, rear. Fits 2013-2018 Mazda CX-5, rear. Confirm rotor dimensions and rear brake configuration before installation. Inspect pads, calipers, and mounting surfaces during brake service, and clean the hub face to help prevent runout-related vibration. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation.

Quality Assurance

MPA Electrical manufactures this rotor as a new coated replacement part with a Q-Shield protective finish for added corrosion resistance and heat tolerance.
