What This Rotor Helps Address
- Rear brake pulsation caused by worn rotor surfaces
- Brake noise related to uneven rotor wear
- Reduced braking consistency from rotors below service thickness
- Parking brake service needs on drum-in-hat rear brake setups
- Fitment replacement for vehicles requiring a 307.7 mm rear rotor
Installation Notes and Tips
Verify rear fitment by year, model, and brake package before installation. This rotor is not for 2009-2014 Nissan 370Z Sport Package vehicles and is not for 2011-2013 INFINITI G37 models with Brembo brakes. Confirm rotor diameter, center hole diameter, bolt pattern, and overall height against the original part before service. BR31387 is a rear rotor application, so it should be matched to the correct axle position during brake repair.
Quality Assurance
DuraGo manufactures brake drums and rotors through ISO-certified factories and builds this rotor to meet fit, form, and function requirements for the listed applications. The brand’s aftermarket brake program is focused on catalog accuracy and application-specific replacement parts.
