The Hawk Performance HB555Y.678 is a brake pad set from the brand's LTS (Light Truck & SUV) line. It uses a Ferro-Carbon friction formulation that the manufacturer developed for full-size trucks, SUVs and vans. The manufacturer lists improved braking over OE pads, superior fade resistance, low dust output, and excellent pad and rotor life, and it claims 20 to 40 percent more stopping power than standard replacement pads. The ".678" in the part number is the pad thickness code.
The case for stepping up from a basic replacement pad is heat management. The manufacturer explains that heavier vehicles with larger brake systems run hotter, so they need pads that shed heat well. That is the problem this compound targets, and it matters most for Armada, Pathfinder and Titan owners who tow, haul or run larger wheels. The pads are intended for iron or metal rotors, so confirm your rotor type before buying. For fitment, this listing covers the 2005-2010 Nissan Armada, the 2004 Pathfinder, and the 2004-2010 Titan with the 5.6L V8. Search terms this set targets include LTS ferro-carbon brake pads for Titan 5.6L, low dust Armada rear pads, and Hawk LTS towing brake pad upgrade.
No. The manufacturer states that its compounds are not compatible with carbon ceramic rotors and that Hawk pads are designed to work with iron or metal rotors.
The manufacturer positions LTS for light trucks, SUVs and vans up to one ton, with low dust and quiet operation. Its HPS 5.0 street compound is aimed at drivers who want maximum stopping power and pedal feel without compromising ABS performance.
Published position details for this part number vary. Confirm the axle position against your caliper or the manufacturer's application data before ordering.
Before starting, confirm that your rotors are iron or metal, since the manufacturer says Hawk pads are designed for those rotors and not carbon ceramic. Torque specifications and the bedding procedure for this exact part number were not confirmed in research, so use the factory service information for your Armada, Pathfinder or Titan and follow the manufacturer's instruction sheet for this pad set.
