A customer needed rear brakes for a 2012 Infiniti FX35 Premium AWD.
Simple request—except the parts catalogue showed two different answers:
- D1393: Manual parking brake
- D1965: Electronic parking brake
Both appeared possible. Only one would fit.
Can You Spot the Clue?
The answer wasn’t hidden behind the wheel.
It was beside the driver’s foot.
Infiniti’s vehicle documentation showed that this FX35 uses a foot-operated parking-brake pedal, not an electronic parking-brake switch.
Mystery solved: D1393-style rear brake pads.
One More Detail Needed Checking
Different pads can sometimes mean different rotors, so we cross-referenced the rear rotor specifications too.
The result?
Both applications use the same 308 mm vented rear rotor. The rotor wasn’t the difference—the parking-brake system was.
The FMPHub Fitment Verdict
- Rear pads: D1393-style
- Parking brake: Foot-operated manual system
- Rear rotor: 308 mm vented
- Confusing customer question: Avoided
Instead of asking the customer, “Does your FX35 use the manual or electronic parking-brake pad application?” we researched the vehicle documentation, manufacturer application notes and rotor specifications ourselves.
Because finding a part number is easy.
Finding the right part number is the real job.
