turning the rotors requires a machine. new rotors shouldn't cost you too much, maybe 200 or less. and most likely you'll only need to replace the front.

 

FWIW, on my toyota truck, i had the worst luck with warping rotors.

i mean 8-10 months was my cycle between vibrations through the steering wheel would occur when braking, and only when braking.

2-3 turnings of the rotors, they are way beyond the min specs.

so i gave in and got cross drilled brembos. that was like 5-6 years ago. went through 2 sets of pads. i have yet to have any rotor problems since.

the other thing i did was buy a torque wrench. once, pep boys did some work on my truck and the monkey who worked on it, just jammed his air gun and tightened it. even when i pointed to their sign on the wall saying "all lug nuts must be torque..."

so as soon as he pulled it from their work bays, i immediately grabbed my torque wrench and big 4-way lug nut wrench. first i loosened the lug nuts and then tightened them right in front of the guy.

then i went to the manager, who didnt do much and i emailed their national office about the incidence.

 

holy crap

 

they are most likely ur rotors like everyone is saying, get drilled and slotted

 

I would never get drilled or slotted rotors unless I went with larger brakes. If you get drilled/slotted rotors without increasing the size of your brake pad, you will be decreasing the contact area between the pad and the rotor.

Also, when control arms are going out, it causes a similar problem. My 2000 528i has worn out control arms, and the wheel vibrates under heavy braking, and the rotors are fine.

 

Yea i had that problem so i went to mpj and got a stoptech bbk in the front and new pads and lines in the rear. best money spent!

 

my steering wheel vibrate/shaky whenever i go over 80... i dont know the cause of it

 

If you are already warping rotors, do NOT get cross-drilled, as they tend to stress fracture between holes.

Slotted are always a good option no matter what size pad/brake system you are using, they tend to dissipate debris/heat.

it takes about an hour to replace rotors and brake pads on all 4 tires, with the proper tools. If you have access to an air compressor and some air tools, a good socket wrench set, a good jack, and some room to work, you can do it yourself. I've done it, and it's really not that difficult.

 

yea your rotors are most likely warped

 

as others have said, your rotors are likely warped, or as StopTech LLC likes to say, you either have a rotor that has "uneven pas residue buildup" or is "not bolted perfectly flat to the hub", FWIW.
