It sounds as if your vehicle might have suffered some serious damage when you hit the curb, especially since you hit the right tire but the vehicle pulls to the left. The fact that your vehicle shakes when braking means it may be unsafe to drive. It is possible that the brakes could fail completely when you need them the most. Have your vehicle inspected and repaired by a qualified mechanic immediately. After that, stop hitting curbs.
Warped rotors
You need an alignment.
You need the front rotors machined or replaced.
If it shakes all the time it is a tire/wheel problem. If it only shakes when braking then it is a brake problem.
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 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.
It is likely a brake rotor has to much run out (warped). There could also be some problem with steering or suspension components.
Does the steering wheel shake worse when you step on the brakes? If braking does not cause the steering wheel shaking you probably just have an out of balance wheel, a bent rim or a faulty tire.
check your tires for a belt seperation. check steering stabilizer shock if equipt. if braking, check for warped rotors.
Warped brake rotor. Have the rotors removed and trued or replaced. Replace the brake pads at the same time.
Tires out of balance, bent wheel, tire defect, or suspension or steering parts worn.
You more than likely bent the wheel or you threw a weight off and the tire is out of balance. Have your tires balanced. They will know if you bent the wheel.
