Rep Power: 0 Resurface rotor or not with current thickness.
Model : 2003 Honda Civic LX
Front Rotor Thickness Min Spec : 0.75"
Front Rotor Current Thickness :0.80" [Certain areas recorded 0.801, Certain 0.804, Certain 0.803]
Front Brake Pads Min Spec : 1.5mm
Front Brake Pads Current Spec : 3.26mm
Issue : steering wheel pulsation during heavy braking. wheels have been re-balanced. alignment done to spec.
So, i am not sure if my rotor is warped, i dont think at 1/1000" it can be considered as warped. Do you guys think there is enough meat left to perform one resurface? [It was never done before]. With a resurface how much material is shaved off?

Re: Resurface rotor or not with current thickness.
Have they been machined at all ? Make sure it is not from rear (press and hold parking brake button and work them on and off at 20mph and see if you get pulsing)
I no longer get rotors machined, simply replace them at 2nd set of pads. And use OEM.

No, they have not been machined at all.
Ok, i will check this step and report back.

Re: Resurface rotor or not with current thickness.
If you think the rotors might be warped you should be more concerned with runout than thickness. The thickness doesn't change from the warping but the runout (distance of the rotor surface from a fixed point) does. Thickness becomes an issue when they turn the rotor. They have to remove material until the warp or runout is eliminated and they can not go below the min thickness. How much material they remove depends on how badly the rotor is warped.

I dont have a dial indicator to measure the runout. The warpness (if any) is not much that is visible with the eye and a vertical scale perpendicular to surface.

I'd get them resurfaced. Any reputable shop will tell you if they can't do it due to the thickness (liability). Depending on which pad I use, I get my rotors resurfaced anywhere from 1-2 times for its life.
