Installation Notes and Tips
When installing the DuraGo BR31365-01 rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify that the rotor thickness is within the nominal range and above the discard thickness to maintain safe braking performance. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Use proper torque specifications for the mounting bolts to avoid rotor distortion.
