We've seen these rotors warping in less then 6 months!
The popular magazines gave the Titan high marks on it’s hauling capabilities however, they did stay long enough to see how the brakes hold up to stopping these loads month after month.
Removing metal from the fiction surfaces to re-true the rotors is only a quick fix. But, it’s the only way to re-true the friction faces. When the brakes are subjected to the same stopping forces that caused the problem in the first place and now with less mass in the rotor, although small, there is a reduction in rotors’ ability to absorb the heat generated.
Not many owners understand the problems with cast-iron. ART doesn’t see these factory parts as "defective". However, Nissan is not using the latest sciences and technology to reduce “
Austenite” in the cast-iron.
Deep cryogenic is a Cryo-Treating process. It's a complex process but, performed properly it promotes better heat absorption in cast-iron by reducing the properties of Austenite and porosity by changing these weaker deposits in the iron into more uniform particles know as"
Martensites". With the addition of gas-porting the friction faces of the brake rotors and employing brake pad materials like Carbon or Kevlar the stopping power will dramatically improve.
Owners who don't use their trucks to tow trailers, carrying work tools or heavy loads are experiencing warped rotors too. This is nothing new to truck owners.
