Just to screw up you guys even more think about this:
There is 2 kinds of warpage of rotors!
1.) Lateral warpage is when the wheel hasn't been torqued properly & has caused the rotor to warp when heated. This type of warpage can be measured using a dial indicator.
2.) The other kind of warpage occurs from the brake pads overheating the rotor under panic, hard stops. This causes the rotor to change colour to a blueish tinge.
The first type of warpage will be felt through the steering wheel, while the second type of warpage will be felt through the brake pedal when the brakes are applied.
Just some food for thought!
