i recently changed my rotors because it was vibrating while braking. it was time for new pads and tires, so i changed them too. The problem is the vibrations is still there while braking at freeway speeds. what could it be? alignment?

 

i have this same problem too. i just got brake pads a couple months ago, and it does vibrate through to the steering wheel also. my dad, who good with cars, says theres no way my pads are bad, and my brake fluid is still at the exact right level [i checked cuz my brake light came on]. so yeah i wanna know what this is also!! plus i got alignment when i got tires bout year ago...

 

When was the last time your tires were rotated/balanced? What rotors did you get? If they were some cheapy ebay rotors, they might have been warped to begin with. Could also be an alignment issue. Possibly a hung caliper?

 

If it's not any of those then check your front struts. If they're blown you would be getting vibration from those as well.

 

hmm, interesting... is that a fact? Cause I've been hearing some strange noise coming from one of my front, year old Tokico Illumina's but I don't want to believe that it's blown. and I do have unexplained vibrations at high speed only and while braking it's pretty bad. Changed rotors twice and still no go with 2 different sets of wheels and tires.

 

Alignment will NOT cause a vibration and possible but unlikely it's shocks. However any other of the above mentioned could be the culprit. My first choice would be anything which is in rotation (rotors, tires, wheels) or something acting on a rotating part - pads or hung caliper.
