So I get a vibration when braking at highway speed intermittently. I would think that it was warped rotors as it feels very similar. However, its not always there, and sometimes if I brake and its there, if I let off and reapply the brakes it goes away. It seems to be worst after longer periods of driving, but does also happen during short trips too. Ball Joints and tie rods are in good shape.....any other ideas?

 

Could be your pads being mis aligned causing them to "grab" and then let go.

Your shocks have a pretty big part in breaking.

I also seen bad hub bearings develope slack and cause a feeling like a pulse.

 

I've been told that it can be a little bit of pad chatter until they bite and seat. Happens to be at highway speeds as well, but not on a consistent basis.

 

Anyone find a way to solve this? Its pretty annoying

 

Like you said in your post...apply, let off, reapply. Seems to be the only way to keep my chatter at bay. Doesn't happen if you just hammer on them from the get-go, only if you feather into them.
