warped rotors
if you are driving and you go to stop, then that means that the front rotors are warped. if the front rotors are bad, you will feel a pulsation in pedal while applying brakes. change rotors on front.
( 2 rotors on the front ) one for each DISC brake
Have the front rotors turned on a lathe at a dealership. check brakes and rotors
You will find that the front brake rotors are located behind the front of your wheel spindle, (behind your wheel and brakes). There you will see the rotors.
The front rotors are out of round or warped, Need to have the rotors turned.
nope ...its the same as any other car for the basic mechanic.
Possible wrong rotors???
Yes. Rotors on front brakes, drums on rear.

Anti-rattle clips not installed properly
Remove the wheel, the calipers and the rotors, reverse procedure with new rotors.
