Product Details

DuraGo engineered the BR900420-01 using its brake component experience to deliver a front rotor that addresses corrosion protection and everyday braking service needs. The rotor measures 12.58 inches in outside diameter, 1.34 inches nominal thickness, and 1.26 inches discard thickness, with a 5-lug bolt pattern, 114.3 mm bolt circle, and 68 mm center hole diameter.

What This Rotor Helps Address

  • Front brake pulsation caused by worn or out-of-spec rotors
  • Brake noise related to uneven rotor surfaces
  • Corrosion on exposed rotor hat and edge areas
  • Reduced braking consistency from heat-worn front rotors
  • Service replacement needs on Infiniti FX35, FX45, FX37, and QX70 front brake systems

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake issues, and inspect pads, calipers, and hardware condition during rotor replacement. The coated finish is intended to protect the hat and edge, so avoid contaminating the braking surface with grease or anti-seize during service.
