Its a superduty deisel that is always towing or hauling its weight or better. Im changing the brakes this week and was wondering how thin is too thin before i need to replace the rotors?%26039;99 F250 4X4 rotors...replacement width?
The minimum thickness specification will be cast into an un-machined surface of the rotor, usually on the hub face. That though is the absolute minimum allowable thickness and the machinist will add to that another .030 allowance for wear and he will not cut beyond the minimum thickness specification plus an additional .030.%26039;99 F250 4X4 rotors...replacement width?
As long as the rotors are smooth and even and the pads haven't worn down to metal and damaged them, you're ok.%26039;99 F250 4X4 rotors...replacement width?
It should be stamped right on them. %26quot;min thickness %26quot;%26039;99 F250 4X4 rotors...replacement width?
When you pull off the brake rotors there is a series of metric numbers stamped inside the rotor near the cooling finns. That number is the minimum thickness the rotor may be machined to and still be leagaly serviceable. You'll need a vernier caliper or micrometers to check the present thickness.
A word to the wise. Select ceramic brake pads as they will not grind off stock from the rotor thickness as fast as OEM Ford metallic pads. AC-Delco, Bendix CT.3 or Hawk - Ferro-Carbon pads.
