So I have tried pretty much everything at this point and still get the vibration, not as bad but still pretty bad. I am convinced it must just be bad front rotors, the hand brake didnt give me any shake.

Agreed, sounds like they're slightly warped.

new and warped already?

Having worked for a brake manufacturer, here's my take.

The number one cause (normally) is a warped rotor. Any brake shop can put a micrometer on it and see if they are out or not.

If not, then I wonder whether you either have the hub back on properly, or the caliper is mounted properly....

HOWEVER: before you do any of this put new pads on.

You could be wasting a lot of time and aggravation, testing stuff that's not broken.

Change them first, then see what else may be an issue if necessary.

Good Luck!

I had to get GT caliper brackets because I was told thats all I needed to upgrade to the larger front brakes. Are the GT calipers and brackets mounted any diff? I sanded down the pads and look smooth so I really doubt its them.

What did you mean by this? Did you swap to full GT calipers and brackets? Or did you put GT brackets on V6 calipers? The brakes are a two piece unit: 1) The bracket that mounts to the spindle and holds the pads and 2) the caliper that bolts to the bracket and slides on the pins. Both of these parts should have been changed to the GT units. I hope you aren't saying you mixed and matched V6 and GT brake parts. If so, that is probably your problem

CDC told me that I only needed to change the bracket that held the caliper. They said the V6 and GT caliper were the same and only the bracket needed to be changed. The GT bracket sets the caliper further back. Is this not true? Are the GT calipers different?

Blair

This seems strange to me... I thought the V6's came with single piston calipers, but it sounds like I was wrong.

Were the brackets side specific? Is it possible that you put the left side bracket on the right side and maybe things aren't lined up right?

Do you still have your stock rotors and brackets? I'd swap those back on. If the shaking goes away then you've narrowed the possible causes to the new rotors or new brackets. Maybe take the rotors to a machine shop and see if they are warped.

Good luck finding the source of your problem

I could try the brackets, not sure if or why the sides would be specific.

Blair

I checked the ford parts schematics and the part numbers for left and right caliper brackets are the same so they aren't side specific. Not sure what your problem is, but good luck getting it fixed up.
