	Unfortunately, machined rotors are even more likely to warp than
	ones that have not been machined (since they are thinner). I had
	an '83 thunderbird turbocoupe (a real piece of trash I might add,
	but that's another story) that exhibited the pulsing at high(er)
	speed braking. I opted to live with it for fear that the
	machined rotors might result in even worse warpage.
