It is engineered as a solid, drum-in-hat rotor with a cast iron body, 5 mounting bolt holes, and a non-directional braking surface to match the specified fitment and braking geometry. This part number, BR31322, is also cross-referenced with Raybestos Brakes 980076 for the same application.

DuraGo manufactures brake drums and rotors through ISO-certified factories and focuses on fit, form, and function for aftermarket brake service. BR31322 is a direct-fit rear rotor choice for Toyota Camry and Lexus ES-series vehicles listed above when replacing a worn or out-of-spec rear rotor.

What It Helps Address

• Rear brake pulsation caused by rotor wear or thickness variation
• Brake noise related to uneven rotor surface condition
• Reduced braking performance from a rotor below discard thickness
• Service issues on rear drum-in-hat brake assemblies
• Replacement needs for Toyota Camry, Toyota Solara, Toyota Avalon, Lexus ES330, and Lexus ES300 rear brake service

Installation Notes and Tips

Verify rotor dimensions, hub fit, and rear axle application before installation. Clean the hub mounting surface thoroughly, inspect pads and caliper hardware for wear, and measure rotor thickness after installation to confirm it remains above discard specification. For best results, follow the vehicle manufacturer’s brake service procedure and bed the pads according to the pad maker’s instructions.

Quality Assurance
