So I am not the only one with phantom brake problems haha. Good to know that I am not alone. I really need to dink around with it a bit and do the tests. I'll keep you updated on what i find if you promise to do the same.
I too still think that it may be possible that mine are just not bedded in yet. I'm afraid to do the bedding procedure again though if i really do have a stuck caliper. I feel that might just make things worse, who knows maybe it will straighten it out.
Could be anything mentioned in this thread so far:
- Stuck Caliper
- Air bubble in system
- Bad suspension part (i.e. thrust arm bushing, etc...)
Is yours a shudder or jerk? One thing I can say is that mine jerks at almost any speed but only if I apply a good amount of brake pressue. It is hower I beleive more pronouned at higher speeds. Its just one quick jerk and then that's it. I didn't really notice if the car veered but then again the first time it happened i was startled and grabbed the wheel.
I should do a slow breaking test to see if it veers.

It doesn't happen much at inital application only when i apply it harder.
I tried slamming the brakes a couple of times to see if it was build up on the rotor from the pads and it seemed to have lessened the shuddering affect.
I was thinking this is more of a pad and maybe some warping of the rotor or material stuck.
I'm using EBC Red and Brembo slotted. I don't see any blueing on any of the rotors and the car drives without shudder or vibration until i perform this around 80 mph.
I also happened to notice this after swapping to my style 87's so I'm not sure if there's some wheel imbalance in the equation as well..
Please keep us posted on your findings!
