you could have worped disk brakes. or your brake pads are not level with your disk brake
try haveing tires rotated and balanced, check for worn suspension and steerign components. does brake pedal pulsate when braking? out of round brake rotors can cause a shake in front end , or could be a caliper hanging up
The pads may be worn out. have it checked out.
Could be a bad "u" joint, or may your driveshaft isn't balanced.
they are not balanced properly.
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
It could be your rims are bent. Or it could be the rotors are warped
Wheel hubs or bearings or could be the CV shafts.
Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts.
Brake pads worn or dirt lodged in brake pad
They probably just need to be balanced
if it is vibration when braking, it is most likely warped brake discs ,which can be skimmed using a lathe or by replacing. if it is vibration when not braking & coming off the power it could be wear in an inner cv joint
The same factors that cuased the ones in the past.
