Have your tires checked and balanced
I had vibration whenever I would brake. I noticed my passenger side tie rod boot was torn, so I had that replaced. Lower ball joint on the same side was torn to all hell, so I replaced that. The tie rod and ball joint on the drivers side were both fine. None of this fixed the vibration problem. I felt it in the steering wheel so I my next thought was warped rotors. I buy new rotors and brakes and put them on. This somehow made the vibration A LOT worse where it feels like my whole front end is shaking but only when I brake. At 40+ mph it is really bad, but lower speeds it isn't as noticeable, but I feel as if the brakes are grabbing, letting go, grabbing, letting go, etc. The pedal also kicks back whenever I brake, which of course is worse as high speeds, to the point where it makes my foot numb. Everything is fine while I'm driving, it just goes crazy when I use the brake pedal.
Anyone experience the same thing or know what might be causing this? I feel like I've checked everything and I can't figure out what is causing it. I would like to mention that the new worse vibration started since the moment I put the new rotors and pads on and got the car up to around 40+ mph.
It's a 01 Jetta.
