the brake rotors are warped. resurface or replace rotors. if the vehicle shakes without applying the brakes, check tire balance.
Get you front end aligned, that should take care of the shakes.
roters need turned. 65;
You need the front rotors machined or replaced.
Check the front motor mount.
if it shakes while your braking your front roters could be warped or if it shakes while your driving try balancing the tires at a tire shop.
Your rotors are probably warped from getting hot during braking and need to be "turned" or replaced. I suggest you take it to a brake shop or dealer.
the brake rotars are out of round or warped.have them machined
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.
check the rotors they could be warped
It is likely a brake rotor has to much run out (warped). There could also be some problem with steering or suspension components.
Check the entire front end. Wheel bearings, ball joints and tie rod ends can all wear and call this problem.
This is usually a symptom of excessive run-out (warped) on front brake rotor or rotors.
