car shakes while i brake?
ok, i just recently changed my rotors and brakes, so i shouldnt have a problem with braking... but its wierd im on freeway and im trying to brake or slow down my car shakes like crazy ( steering wheel ) if it just did my brakes then why is it having the shaking problems? can it be my tire.. one of my tire is almost gonna blow.. can that be the factor?

Re: car shakes while i brake? (boosted_LS)
The cheap autoparts rotors are so cheap that some I have used were warped right out of the box.On my own car I turn the new rotors before I put them on.For sure check the wheel bearings and caliper bolts,etc...

My buddy had this problem, thing is it could be a number of factors...first make sure your alignment is straight...this will definately cause it to shake...also, are there diff/ tires ont he car or does the car have all the same tires and threads? That could also lead to that problem...hope that helps

Re: (DC2KinG)
Did you burnish the new pads and rotors? (might have warped them out the box) What kind of pads did you buy? (compound) Are you using more then one tire brand? Is the front-end aligned? And of course, you got em at autozone dude. Turn them, and when they cant get turned any more get some brembo blanks. And get a good street pad compound and tires (I.E. Axxis ultimates or Hawk HP series) (toyo proxes, khumo ecsta, IT'S A MATTER OF OPINION SO SEARCH)

Re: (Medek)
Read this article on the MYTH OF WARPED BRAKE ROTORS:
http://www.stoptech.com/whitep...h.htm
If you didn't break in your pads/rotors when you installed them, you probably left uneven pad deposits on the rotors, so that it gives that pulsating feeling when coming to a stop. Since they are still new, I would try breaking them in using these methods. If that doesn't work, you could install a set of more abrasive pads to clean off the deposits, then go back to OEM when they are gone. Or, you could try some garnet paper to sand them off.
From Stoptech:
OK, now that you hopefully better understand why the steering wheel is shaking out of your hand, what can be done to cure it? Turning the rotors will take care of it, but you will be shortening the life of the rotor and decreasing its ability to absorb and control heat, as there will be less mass in the rotor after turning. Also, turning a 2-piece rotor that uses floating attachment hardware between the rotor and hat can be tricky. We have had very good success running an aggressive track pad at lower temperatures on the street in order to scrub off the rotor surface. We have found the Hawk Blue 9012 race pad to be very effective. At lower temperatures it is very ABRASIVE, not becoming ADHERENT until it reaches it's optimal operating temperature. If it is used with a few firm stops at a time, not getting too hot (we want to remove material, not transfer more), it will often remove the source of vibration.
A WARNING: Do not leave an abrasive pad in the caliper longer than necessary to solve the problem. We have had rotors destroyed in under a week by leaving the abrasive track pads in on the street.

when my cousin, who was a mechanic used to change my pads and rotors, he added some brake compound to the pads. might be something to make sure it doesn't warp so quickly and creates a good surface to rotor. did you add that compound and let it soak in?

Re: (RevOnRacerz)
It is not the rotors if you do not feel the brake pedal pulsating... If the pedal pulsates, then your rotors are slightly warped... Otherwise it can be alignment or tires... And since you said that your tires suck, then I'd go with that...

Re: (95IntegraLSR)
wrong, its the rotors.
i mean, my steering wheel was shaking really bad, and i didnt feel my pedals vibrating.
after i got my rotors resurfaced, the steering wheel stopped shaking.
if its ur wheel or alignment, ur steering wheel will shake or car will pull to one side while driving. not while braking.
