Vibration when slowly braking

Hello,

It sounds like the brake rotors are wrapped. As you press the brake that is the vibration you feel.
Keep in mind that the warpage of the rotor cannot be detected by a simple visual inspection.
You will have to do a lateral runout check using a gauge. Look below for the runout testing procedure.
If the rotors have excessive lateral runout, then they need to be replaced.
On this vehicle the knuckle needs to be removed in order to replace the rotors.

I have attached the replacement procedure below.

Please let me know of any questions.
Thank you.
