car front end vibrates when braking,why?

probably front rotors warped. if they're still above the legal thickness get them machined and it will probably sort the problem out. otherwise replace the rotors.

Your Rotors are probably warped, presuming you have disc brakes on the front-end, although Iguess you could get it from the back end also, however so much of your braking is handled by the front brakes thats usually the best place to start. You'll probably need pads also, as the rotors tend to warp really bad when you have worn out the brake pads due to excessive heat being generated. If that isn't it it could be a number of very complicated and potentially expensive things. Just make sure you find a knowledgeable and honest mechanic!!!!!! JFREDMUGS01

some various issues could reason that; being out of alignment, tires being out of stability, or a foul cv joint on the front-wheel-force axle halfshafts. Rotate the tires first to ascertain if issues advance or replace- that would fault the tires. Have the alignment checked and glued each and every 4 years a minimum of. The axles are actually not somewhat ordinary to diagnose till you eliminate them.

usually when there is a vibration during brakeing the cause is bad roter's, but there could be other issue;s with the front end,have it inspected, good luck
