Vibrates or pulses along with the speed you're going? Vibrating COULD be ABS erroneously kicking on. More of a pulse in the pedal that corresponds with speed is a warped rotor most likely. It's not worth having these rotors turned/machined. The thinner they get the easier it is to warp them. The price of new rotors is not THAT much more than the time and cash for having them turned.
I have an '05 Corolla with 160,000 miles on it and this thing goes through rotors....I think I put new rotors on a year ago, maybe more, but the pedal is already pulsing when i brake. And 90% of the time they are quiet, but every so often they grind....they will grind coming to a stop....then a few blocks later when coming to a stop there's no grinding.
This weekend it's time to have a look at the brakes....again.
