You're RIGHT though.
Not a "Warped" Rotor, just uneven Deposits.
It'll do it every time.
If your Rotors Really are Warped, about the only way that'll happen is by hitting Cold Water (ie. Washing) onto Hot Rotors.
If it's not that, you've got something disconnected...????
Um, you can also create small heat cracks in the rotors, but that would take repeated sudden deceleration from, say 150 mph to 65 mph, like you were coming up on a Highway Patrol unit and you had to slow down real fast... don't ask me how I know all this...
Sounds like the brake rotors are warped which will cause the steering wheel to shake when applying the brakes.Best thing to do is have the brakes inspected and measure the rotors with a micrometer if they are still within factory spec they can be resurfaced if they are at or below factory spec they will have to be replaced also have the brake pads inspected for wear and if low replace them too.
Wow, that's pretty cheap. I would say it would still be worth it to have them resurfaced if you could remove the rotors yourself and just have the shop do the resurfacing. That would probably be pretty cheap.
