more vibration, it just wont go away!

[Wes325]

OK, its getting worse. A while back I had a hard vibration under breaking so I replaced the front rotors. Problem was solved, after a month of driving I thought I could feel it very faintly starting back up again but I thought it was just in my head. Its probably been 4 months now and its definately not in my head, its very strong and only when under breaking(let off the break, it immediately stops, obvious!)
Could something be causing my rotors to warp again or is it something else thats causing the vibrating under breaking. It vibrates under ANY type of breaking. Mild to heavy breaking it shakes so hard that the steering wheel shakes very hard and is loud but if its very hard fast breaking it will not shake for a second as soon as i press the pedal and then go away. Help me out guys, any advice is very appreciated. Thanks

have you replaced the Control Arm Bushings lately?

[Wes325]

that would be a negative, think that would cause it just to vibrate or would it warp the rotors too? Sorry if that is a lame question, Im just looking for what all could be damaged now. Thanks for the input!

I don't see how it could warp the rotors.

But worn control arm bushings cause steering vibrations under breaking. You should check them out, and if they are worn, it'd be a good time to upgrade :D

What's the mileage on your car? The chances are they are worn, so you could replace it and see how it goes.

Is the Brake* pedal pulsating?
Perhaps you purchased low quality rotors, or you have a stuck caliper thats overheating one of the rotors.
Get some german, or brembo ones.

pull the calipers, rebuild them, make sure the guide bolts are lubricated, make sure there is no binding, bleed the brakes, get new rotors, get new pads.

i had a seized guide bolt once that ruined my rotors. i also unknowingly got grease on one of my pads once that caused hot spots ruining another rotor.

How do you know the rotors are wraped? Have you miced them to see if they out off? Does the brake pedal pulsate?

[Wes325]

The break pedal doesnt pulsate at all, what would this mean? The rotors i put on the car last were brembo blanks from BMA. Hopefully I wont have to get the calipers rebuilt. The mileage on the car as of today reads 124K

control arm bushings.
Go kick the tire back to front, see if it moves.
If so, time to get new ones. Even if you still dont see it move, you are describing the symptoms of worn CAB's.

to really check your front suspension for wear you have to lift it off the ground. I couldn't move my wheel at all with the car on the ground, but once I jacked it up it was pretty obvious how bad my ball joints were.
