Detailed Description

The MPA Electrical BR5577G brake rotor is engineered for front axle service on select 1991-1996 Buick Roadmaster, Chevrolet Caprice, Chevrolet Impala, Cadillac Fleetwood, Cadillac Commercial Chassis, Cadillac Brougham, and Oldsmobile Custom Cruiser models. Its OE-style vane layout helps move heat away from the braking surface, supporting stable stopping performance during repeated stops and everyday driving. The coated surface adds corrosion protection, which is especially valuable in wet, salted, or high-humidity environments. If you are replacing a worn front rotor on a Buick Roadmaster or Chevrolet Caprice, BR5577G provides a direct-fit service part for the listed applications.

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

Common Problems This Rotor Can Address

• Brake pulsation from a worn or uneven front rotor
• Noise caused by rotor surface wear or corrosion
• Reduced stopping consistency from heat buildup
• Rust on exposed braking surfaces
• Front brake service needs on listed GM and Cadillac models

Installation Notes and Tips

Confirm rotor diameter, hub configuration, and front axle fitment before installation. Inspect pads, calipers, and wheel bearings during brake service so the new rotor is not affected by related wear. Clean the rotor friction surfaces before use if any protective residue is present from packaging or handling. Verify the vehicle matches one of the listed front applications before ordering BR5577G.
