Brake vibration is where a shaking motion occurs when the brakes in a car or othervehicle are deployed. This can vary from a slight shaking to a quite severe ..

Very unlikely a bad alternator is going to cause a steering wheel shake even if the alternator is seriously out of balance. In that case a high frequency vibration will run through almost the entire car and the alternator will soon self-destruct.

There are a few reasons why a steering wheel might shake and mostly these relate to the integrity of the front wheels and tyres, the roundness, the radial and axial run-out, the balance and the compatibility with each other and the vehicle. Problems with the wheels and tyres can further be aggravated by steering/suspension wear or misalignment, worn shock absorbers and even binding brakes or warped brake discs.

The rear wheels and tyres and suspension and brakes are also important for a smooth ride and could conceivably cause a steering wheel shake, though a different sort of shake to that caused by the fronts. In this case the vibration is often felt mostly through the seat of the pants and from the seat back.

If you are getting shaking when you brake then I would get your brakes checked. You may have a warped rotor or possible one brake pad that is worn unevenly or even broken. It is also possible that you have a caliper that is binding.

great danger there. dont go fast.
can be tires out of balance (tire weighs feel off)
or wheel falling off (ever check the lugs)
tire bad. (bulged, delaminations , man killer tires, like Firestones)
tire rods balls, ready to fall off (more man killers)
ball joint ,ready to fail. and far far worse...
why not get the car serviced, have them check it out before.... bad happens.
noise and vibration or shaking on any machine means , doom is coming. in most cases,.

If the car shakes while you are pressing the brakes, you likely have warped brake rotors (usually the front brakes are the culprit because they provide most of the stopping power and accumulate the most heat). If that's the case, you should have the rotors and pads replaced.

It is a common issue and relatively easy fix.

Sounds like the rotors are warped,Take to a brake shop and have them checked or replaced.

Front shocks are week

Certainly sounds like a partially, or seized caliper hanging up, which has warped rotor. What exactly did they replace at brake job, do you know? Either way they need to be rechecked.
