Ummm,,, Actually thinking out of round rotors. The easiest way to check is with a "dial indicator". What you're looking for is what's called "Run out". With the wheel off, set the probe of the dial indicator against the mid to outer section of the disc and rotate the wheel./ There should be no more than a couple of thou variance in one complete revolution of the wheel. Check both sides, as it only takes one side to be out to wiggle the steering wheel. If it only does it sometimes, that's indicative of BOTH sides being out of round, as every time you turn a corner, the wheels orientation to each other is changed, which results in that sometimes, the out of roundness on one side cancels out the out of roundness on the other side, and sometimes amplifies the symptom.

If you find the disc is not "true" ... return it! Do NOT let them turn it, especially if you paid for drilled, dimpled or slotted.. One of the problems with the SVX is that it's a relatively heavy vehicle, and therefore generates a significant amount of heat under breaking. Turning the rotors, even if the disc remains "within specs", diminishes it's ability to absorb heat, and diminishes it's ability to resist warping from, shall we say, enthusiastic driving. It wouldn't hurt to check the rears, while you're at it. If they are out of true, you wouldn't feel it as much, but ANY out of roundness plays hell with the ABS when you approach threshold.

It's actually doing the same thing at slower speeds, it's just not as noticeable, as the frequency of the pulsing is directly related to road speed. It's also relative to braking force.

It's pretty much a certainty that the issue is in the front set. The basic rule of thumb is that if you feel it in the steering wheel, it's the front end, if you feel it in the seat of your pants, it's in the rear end.
