maybe the car need to be linged up n check the power steering.
Tire out of balance, bent wheel, or if it vibrates only when braking you have a warped rotor.
Most likely warped brake discs
If it shakes all the time it is a tire/wheel problem. If it only shakes when braking then it is a brake problem.
vibrations while slowing or braking? Get the front brake rotors checked.
This can be a warped rotor or tire out of balance. If it only happens when braking it is a warped rotor.
Sounds like your front brake rotors are warped.
Your AC should have NOTHING to do with your barking system, as it is not tied into the vacuum of the engine. If your wheel shakes under braking, then you need to replace your rotors and pads.
If your car vibrates when you are braking, you might have pads that have worn unevenly. You can have the brake pads inspected to see if there is wearing on the drum or if you have a problem with your rotors.
If it varies with driving speed, look for an out-of-round tire. If it vibrates only when braking, you probably have a warped brake rotor.
Replace the power steering pump.
vibrations are not bad for a car it vibrates every time you drive, but for safety i really think that with a flat spot on a tire it is not safe to drive on.
When the system is active this is normal due to the braking system being applied to a spinning wheel or a wheel that in under or over steering.
