Uneven application of braking power at high speeds, caused by the heat that is made between the rotor and the brake pad; this is causing uneven stresses in the rotor. Such heavy brake usage aggravates the situation by providing uneven wearing along the circumference of the braking surface.
However, other possibilities occur with loose suspension ortire wear; i.e.wheels out of balance.
front end is worn out
Check the front motor mount.
Front brake rotors are warped
Mine had a warped rotor and i had it replaced and it helped
depends on when it shakes if it shakes when you put on the brakes-warped rotors otherwise it could be ball joints, steering joints, wheel bearings or even out of balance tires
Tires/wheels out of balance?
you need a front end alignment
YOUR FRONT ROTORS ARE WARPED. YOU NEED A BRAKE JOB.
Get you front end aligned, that should take care of the shakes.
Sounds like a motor mount or a transmission problem.......
Your automobile may have a tire out of balance or a worn part in the front end causing this "shimmy" effect .
You probably bent the wheel. Have the wheel inspected and replace it if it is bent. Make sure they inspect the tire for damage. I would also have the front end realigned.
