Car drives perfect, no out of balance on the highway, no pulsation in the wheel normaly, brakes are smooth no pulsation, car tracks strait not veering, problem is every so often usually in deceleration, the sterring wheel shakes almost like a tire is out of balance bad. It is not speed specific, nor directional, seems to be random except the deceleration part. Tires are newer, brakes are newer, very solid car, any ideas?

The wheel wobble could be balance on road wheel,check n/s track rod end for wear this could be why the tyre is wearing.If you change track rod end get it re-tracked and the front wheels balanced...Good-luck...
When you get a vibration at high speeds when you hit the brakes the rotor/s are very slightly warped. Depending on miles, you may be able to get them turned / surfaced. One other thing is if you don't drive it to much, they can rust and cause the same problem. Hitting the brakes a few times on the highway will smooth them out.
There are many things that can cause a vehicle to shake such as an unbalanced tire,or if the vehicle shakes under braking and the brake pedal pulsates,there's a good chance that the rotors might be warped.
If the car shakes going down the highway it could be anything from a wheel that needs to be balanced to worn bushings in the front end.
All of these things should be investigated when you have an issue such as this.
if you get a pulsation/vibration when you apply the brakes than the brake rotors are warped. If the pulsation/vibration can be felt as your driving without applying the brakes than some common causes could be a tire out of balance, a separated tire, or a bent wheel,
The most common cause of brake pulse is wheel bearings, because the rotor wobbles.
The way to tell is that you will also feel it through the steering wheel, when not applying brakes.
If the rotor wobbles, it will also make the brakes spongey, because the wobble will cause some piston retraction, causing a longer throw when applying.
It is usually the fronts that go bad before the back. And one side before the other, often because a bad seal allowed water in. But you can tell by jacking up and feeling for play.
If not a wheel bearing, then I would consider ABS problem, or the rotor was installed wrong.
on a clear road try gently applying the E brake, see if that produces the feeling, I would say either a rotor is warped (wobbled from side to side due to heat disatortion) or a drum. It is not easy to see these faults, with a wheel off you need to turn the rotor and look for the wobble, it only takes a wobble of 1/16 or 2mm to make the brake pedal pulse. This is a large safety issue as your brakes will be impaired.
