If the steering wheel shakes, but to car doesn't, when applying brakes - your front rotors are warped (if you have disc brakes)...if you have drum brakes, the drum could be cracked or the pads worn unevenly If the whole car shakes, and the steering wheel only seems to react to that, when applying brakes - see above statement, but apply to the rear end. If the whole car shakes, including the steering wheel - all four corners are bad, and you're an accident looking for a place to happen soon. In any case, go to your nearest service center ASAP.
yes
Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts.
Applying the brakes.
Normally this is caused by warped brake rotors.
A car shaking while applying brakes is most likely caused by worn a brake pad. Check the brake system at all four wheels to find the problem.
brakes, or no sun
Applying the brakes with your foot!
If when applying the brakes ,roorts. If when driving only a bad tire.
warped rotors(brakes)...most likely front ones
yes, but only when the brakes are applied.
STICKING BRAKE CALIPER
Good question. You may have an antilock brake circuit that is not sensing the brakes correctly and improperly correcting. Anti lock pulses the brakes when you apply them. I don't know if this is perfected or not.
