Overview
The Baer Brakes 31329-020 is a pair of rear Claw performance brake rotors for the 2004-2010 Infiniti QX56, the 2005-2015 Nissan Armada and the 2004-2015 Nissan Titan. Each rotor is a one-piece, full cast iron vented disc with a slotted and cross-drilled friction face, sold as a direct replacement for the factory rear rotors.
The slots and cross-drilled holes give gas and dust from the pad a way out during braking. This supports a steadier pedal feel and reduces brake fade. The zinc-plated finish looks bright when the rotors are visible behind open-center wheels. The kit is a rear axle part with six lug holes.
Key features
- Slotted and drilled friction face that vents gas and dust
- Enhanced vane structure and premium materials for cooling
- Premium, mill balanced direct replacement rotor
- Chamfered cross-drilled holes to help reduce stress cracking
- Zinc-plated finish for open-center wheels
Choosing the right setup
A rear rotor works with the parking brake and the rear pads, so uneven wear on one side often shows up as pulsing or a pull under braking. Vented rotors dissipate heat better than solid discs, which matters when towing or descending a long grade. The rotor is only part of the job; the pads, caliper hardware and fluid condition all affect how the brakes feel.
Look at the rotor face for deep grooves, blue heat marks, or a raised lip at the outer edge before reinstalling. Slots and cross-drilled holes are designed to clear debris, but they can also let cracks start at the holes if the rotor is overheated or hit hard. Replace rotors in pairs on the same axle so braking stays balanced from side to side.

Vehicle fitment
It fits the 2004-2010 Infiniti QX56 (RWD and 4WD), the 2005-2015 Nissan Armada (RWD, 4WD and AWD) and the 2004-2015 Nissan Titan (RWD and 4WD).
Front axle positions are not covered. Other Nissan or Infiniti models outside the three named vehicles are not covered. Confirm your vehicle’s year, model and drive type before ordering.
Installation notes
The kit does not include an ABS tone ring, so the existing tone ring should be reused. Because the bolt pattern is six lugs with a 140 bolt hole circle diameter, check the pattern against the vehicle before installing. Have the work done by someone experienced with hydraulic brake service.
What’s included
A set of two one-piece vented rear rotors, one for each side of the axle.
Not included: ABS tone ring, brake pads and hardware.
