I have when I brake. It feels as though its coming from the front. I changed the rotors and not the pads and the vibration still occurs. Took it to the dealer first they said the front rotors were warped even though I only had them a week. One rim is bent in the back. They said I have hot spots in the rear rotors which they recommend resurface and replace pads. I have a vibration which always I feel on the drivers side in the front. They also say the tires that I had in the front now rotated to the back are bad due to high roadforce over 24**

Can the vibrations I feel when braking stem from bad rear rotors/brakes?
Alignment is good except left rear camber -1.7.

 

Is the vibration felt thru the pedal or the wheel? Have you tried to re bed the pads? May have some uneven pad material deposits on the rotors.

 

I feel it in the wheel and its hard to stop due to the shimmy from high speed

 

Try changing the bent rim to your donut and see if it goes away. If so, replace the bad rim. Some to try and rule out.

 

I am confused, the bent wheel has been rotated to the front now? did you abuse your new rotors? did you bed your pads?
High speed shimmy felt in the wheel is not coming from your rear brakes.

 

bleed your calipers left front then opposite side rear (right) and then right side front and then left rear. Make SURE that you are adding brake fluid as needed and then once all calipers are bled. Retighten everything to spec and then do a few hard stops (to the point where abs engages) to purge air from the abs control module.

 

No the bent wheel is still in the back.

i will try to purge. Another recommendation i heard was to sand the brake pads since they were on the old rotors then rebed them.

 

Sounds like warped rotors to me. Did the problem go away for a bit once you put the new rotors on? The OEM rotors warp so quickly, I wouldn't be surprised if it happened again.

 

No once I hit the road the vibration (not braking) was till evident along with while bedding there was vibration (while braking).

These are stoptech pads and stoptech rotors.

 

Wait a second... you said "Brake vibration." If the vibration happens when you're NOT braking, then it's probably NOT the brakes. Could be something easy like an out of balance or bent wheel; or something more expensive.
