ok well i was getting some bad vibrations after i changed my brake pads.... so i decided to get my rotors turned too... so after installing the newly machined rotors and driving it around.. it felt good, very smooth braking. Then, a couple weeks later i notice that the vibrations started coming back and now it's pretty much where it was again. HOW CAN THIS BE? I talked to the guy that helped me with my brakes and he said that it probably isn't the brakes, and i agreed because it seems unlikely that they would be warped again. He said it might be tie rods or wheel balance...
has anyone had any experiences like this? does anyone know what could be causing the problem? thanks.

 

Could be tie rods, could be that your rotors don't have much meat on them and they are warping again from the heat of the pads...

 

well since it was smooth after the rotors were resurfaced id say you warped them again ... the break in time of new pads causes more heat inorder to seat the two surfaces together. did you measure your rotors before you resurfaced them? they might be to thin and not able to dissipate the heat properly. go get some new rotors

 

definately the rotors are too thin ive had this happen more than once.. only other thing is if you hear noise with it sometimes a caliper isnt hooked on right or something and it skips but dollars to donuts its the rotors get good new ones

 

ok this might sound like a stupid question but can you get drilled and slotted rotors machined?

 

You may have over tightened the lug nuts when you did the brake job. That is a big contributor to warped rotors. The damage may already have been done, but next time torque them to spec.

 

well tomorrow im gunna go to napa and buy some new ones.. if not napa then speedway auto parts

i think the whole "turning rotors" thing is a waste, better off just getting new ones.

 

ya.. unforntunately i guess i learned that the hard way.
