If it were out of balance tires or an alignment issue you would feel vibration in a narrow speed range as the natural frequency of the system is approached.

The only ways I know of to fix a warped rotor are to have it turned (machined flat) or replace them. Replacing them would probably be the easiest, and possibly the cheapest, solution - this also gives you the chance to upgrade the rotors.

Caution

I dont seem to have an issue at all when braking but you could replace your rotors or as stated above -- get them turned (machined flat) <- cheapest way

If your rotors are warped you can have them machined, but I'd replace them personally. And no, my brakes don't cause any vibration when slowing from a high speed run, but then I don't DO high speed runs unless the road is empty and straight. And then, I usually reduce speed by coasting either in 5th or downshifting to 4th. I do very little high speed braking, if any.

Rotors will warp on all cars, just to make it clear. If you feel the steering wheel shake when hitting the brakes, its the front rotors. If you feel it through the whole car, its the rears. The fronts are more prone to warping than rears since more braking force is applied to them. I would replace them to ensure a good repair. I own a shop and turn rotors all the time. I usually dont suggest to customers to replace them if they can be resurfaced because 95% of the public is too cheap, and absolutelyhates spending money on their cars.Even if it means their safety is at risk if they dont. So, setting up the rotor on the brake lathe takes some practice to make sure you get a good cut. I dont go through techs very easily here, but whenever showing a new guy (shop-bitch) how to set it up, I stand there personally several times to make sure it gets done right. I hate comebacks. Brakes are easy to do, but not getting the rotor set up correctly will just as easily create a return visit due to noise caused by rotor run-out. Because of that possible problem, and since 95% of the people on this forum will HAPPILY spend money on their cars to make sure its done right, my suggestion again is to buy NEW rotors.
