OK when i brake my frony ends shimys and u can feal it in the steering wheel, is this just an aligment issue or a brake issue? thats the only time it oes it when i brake!!

 

sounds like alignment. ive had brake problems in my car, my moms van, and my dads Jimmy, nothing like that before. does it feel like an ABS system or is it just moving left to right?

 

It actually sounds like warped rotors.

 

yea i think when i brake it will shimmy and want to go to one side!!

 

Well, it could be a combination of the two. When you have warped rotors, you will feel your steering wheel shaking back and forth pretty hard when you really get on the brakes, and eventually you won't be able to hold it still. However, if your car is pulling hard to one side, that is more likely an alignment problem.

 

How do roters warp and what can u do to prevent this??

 

They tend to warp naturally over long periods of time as a result of the incredible amounts of heat generated by braking. Also, if you drive with worn out pads for awhile, the metal-on-metal contact can weaken certain areas of the rotor, making them more prone to this heat warping. Finally, warping tends to come on more quickly in colder climates, since the rapid temperature differential cools the rotors so quickly.

So, long story short, there's not a whole lot you can do to prevent warping unless you get some aftermarket rotors (slotted) that are designed to dissipate the heat quickly and evenly. However, a resurfacing job or a new set of rotors coupled with regular brake pad replacement can extend the life of the rotors well beyond what you would expect.

 

this probably wont be it..but make sure your lug nuts are tight, my buddys were loose and eveytime he put the brake on it would shake really bad

 

already done that i hope its just out of aligne but im geting a aligment tomm so we will see if thats fixes it!!

 

I have the same problem, my sterring wheel shakes back and forth when i brake but i had an alignment done like 4 or 5 months ago so i beleive i have warped rotors.
