so, after 1.5 hours in poring rain, i've finished changing the rotors and brakes.
didnt have many choices in town here, ended up getting Zimmermann rotors and PBR ULT ceramic pads.

After about 50 "speed up slow down" i took the vehicle to highway... no shaking at all!! :rofl::rofl::rofl:
It still feels kind of weird, im planning to take it for wheel alignment somewhere else now, don't have faith in place it went last time.

I did do the pretension of bushings (loosened the bolts and lowered vehicle to its normal height and than tightened the bolts).

When i had new rotor in place it looked like it was on a slight angle, like it was turned, i looked at other wheel - straight...

:dunno:

New rotors did solve issue with shaking while braking :D

Good news!:thumbup: Just be sure not to hold the brakes while they are at their hottest. That tends to leave a little brake pad material roasted on your rotor and you will have the same issue.

+1 stuck brake caliper

Had this same exact problem. The dealer kept changing out my rotors and a suspension component. Each time the problem came back after several thousand miles. Finally they found out that one of my front brake calipers was stuck causing the rotor to overheat and eventually warp causing the steering wheel to shake under braking.

:dunno:when i had my brakes off yesterday i noticed that seal on brake caliper is broken - will be ordering repair kit (56$ canadian from dealer)

Item number 10 http://http://realoem.com/bmw/showpa...75&hg=34&fg=05

Dont want my rotors to warp again, the rotors i took off and pads were not that worn out. Pads are 15mm thick(including metal part)

Also my vehicle is going for wheel alignment on friday, we'll see how well it was done last time. (goin to a chevrolet dealer :rofl:):dunno:

update:
3 days with new rotors and pads - my vehicle is pulling to one side when brakes are applied, got small shake when i was slowing down from 85km/h :wow:
Will be buying a rebuild caliper tomorrow, found one locally for 120$ and a repair kit for caliper is 56 and it has to be ordered in.
I guess the caliper on drivers side is what caused rotor to warp.

Will keep you guys posted once i replace the caliper.

Solved, warped rotors
 

I installed new Brembo rotors this weekend and the shimmy is gone for now. The Brembo rotors are $60 each with free shipping from Amazon, pretty good deal if they do not warp. They were made is Brazil?? I did not see any indication of a stuck caliper or uneven wear on the brake pads, as these pads and rotors had only 10k miles on them are were all factory BMW.

Floydturbo** just wanted to get an update.. how is the X running? As far as your posts go, you replaced the front wishbone and then got new rotors correct?
I got new rotors on and I have a slight shimmy at 75 as well now. wishbone is stock and never been changed, thanks!

My shaking came back... Started shaking very badly all of a sudden...
But i found the problem!
The new pads that i put in, the edges had to be filed off, they were not smooth so outside pad got stuck one side :-(

What kind of pads did you use? I have never heard of this before. Do you think a stuck piston may have caused this?

i dont even remember what was brand name :(
i checked piston its fine, the other site i changed completely, but i will be rebuilding the other side too, just to make sure :)
it is strange
i had to force pad to come off the brake carrier.
