Vibration Under High Speed Braking
only at speeds above 50mph or so...
yes, i got new rotors in front...and all the pads still have a good chunk of meat left on them...what else could be causing this? it's not fun feeling the steering wheel shake like this when i'm trying to slow down in a hurry...to say the least. |
The steering wheel shakes when braking... classic sign that the rotors need to be machined. Where'd you get the rotors?
EDIT... also, have you balanced your tires lately? |
..............word.................

when you replaced your rotors, did you replace the pads as well? I hear it's not good to replace rotors w/o new pads (I don't know from personal experience, pads are something I replace when I do any work where the tire comes off, since they are lifetime pads and all).

Do not use old pads with new rotors.... or any other rotor for that matter. Pads do not wear evenly. They are no longer parallel after some use. If you can imagine, the outside of the rotor turns faster than the inside (closer to the wheel bearings), so the outsides wear faster. It's just as bad as installing new pads with old, un-turned, rotors.
And then, even with new pads and rotors, you might experience some shake. The fsm specifies a maximum of .005" runout on the rotors. Most people can't easily check this. So, you might just try and determine which rotor is running out, or is out of balance a little, and rotate it one hole on the lugs. This has been known to improve things. If rotating the rotor one hole doesn't help, rotate it another hole. If you have new pads and rotors and you can't get rid of the vibration, there's a good chance that you have a bad rotor. |
If the vibration is in te steering wheel then its fron rotors if it feels more like in the seat thn its rear rotors $.02
|
have you had your tires balanced lately? If it vibrates, it could just be noticeable during high speeds and braking.

It's likey your tension rod bushings.....surprised nobody else has suggested this.

91 has a point. Also I would check your tie rod ends (inner and outer, back and front) to see if they are loose.
