That means person inside car is either too heavy or something like a toy is caught in engine
While driving, apply the brakes gently for a short distance, as you maintain your speed.
When driving downhill, gravity increases your vehicle's speed, making it important to manage your speed effectively. Shifting to a lower gear helps use engine braking to control your descent, reducing reliance on the brakes. Additionally, applying your brakes smoothly can help maintain a safe speed without overheating the braking system. Always stay alert and adjust your driving as needed to ensure safety on steep slopes.
you have to be more specific for a proper answer... at what speed does it shake?.... 40mph> ? what do you mean mist?
You have a wheel balance problem. Did you hit a curb? Did the wheel get encased in mud? Wheel balance fall off? Try changing positions of the wheels to isolate the problem to a specific wheel or tire? Or is the shake connected with engine speed? Vehicle speed? While using the brakes it gets worse or no effect? See how specific you can get the problem and tell your mechanic what you know.
Check your wheel bearings, tie rod ends, balljoints and CV axles. A bent rim will also cause a shake at high speed.
shifted or broken belt in the tires
needs wheel balance .maybe needs air in tires
"Fanning the brakes" refers to a technique used primarily in motorsports and driving to control the vehicle's speed, especially in situations where sudden braking might cause loss of control. It involves rapidly applying and releasing the brake pedal to prevent the brakes from overheating and to maintain traction while navigating tight turns. This technique helps drivers manage their speed more effectively without completely locking up the wheels.
The most likely cause is a warped rotor. It can also be other things so have you brakes and suspension inspected.

Because you will skid and lose control of the vehicle. Unless it is equipt with anit-lock brakes.
