OKay so recently i noticed that when im going 40-45 and im slowly hitting the breakes, my steering wheel starts shaking alot and its been getting worse, and the steering wheel doesnt seem so straight anymore, slightly crooked, does that mean i need new brakes? or is it alignment that might be the problem?

well could be either of those things.
check your rotors, and your alignment. maybe you hit a curb? or a pothole that might have caused a misalignment.

if u have aftermarket wheels do u have a hubcentric ring?

Wheel location would be alignment, shaking on braking would be warped rotors or uneven pad wear. You pop the wheel off and see if you have any scoring on the rotor or the pads look funky?

yea you would have to resurface the front rotors unless ur brake pedal is also pulsating the resurface all four rotors

Rotors need to be resurfaced for sure. I had this problem last year.

Yeah if it was alignment or spacer or wheel issue the vibration would also be noticeable during regular driving conditions.
Since it's only noticeable while braking at highway speeds it is clearly because of the rotors.
I currently have the same issue with my 240, but it's not too bad yet.

hmm rotors eh, alright well thanks for the tips, i will get all that checked out!

Currently my IS is doing this too. I have been holding out on getting them resurfaced and I dont know why my SA suggests having them resurfaced with every pad change. I hear that it severely weakens the rotors and could cause serious problems down the road. And I also know that Mercedes does not do any rotor resurfacing and instead tells their customers to replace them instead

alignment should not affect vibrations in steering wheel. vibrations in wheel are caused from tires being out of balance and if rotors need resurfacing, which is your case.

To clear this up machining rotors multiple times does not weaken rotors,the manufacture has a specification of how thick the rotor can be so you can machine them until they get that thin. and mercedes uses composite rotors and you cannot turn those, i mean you can but its not recomended. for ur problem its your rotors plain and simple hope i could help!

Could it possible be from mismatched tread on tires? I popped a tire last week and now my steering wheel does the same. I replaced it with a tire with full tread while all the other are pretty low.

When applying the brakes and the steering wheel shakes it time for the rotors to be turned and maybe new pads

Get your rotors resurfaced
