steering wheel shacking when braking




my steering is shacking very unpleasant.
i thought it was the warped rotors but i do have a new ones that i installed about to weeks ago...so i doubt its that.
also rear ones were changed about a year ago they all seems fine.
one thing i noticed though which may relate to this issue is that when the car is off , and i turn the steering wheel left to right and right to left it makes a sound like something is loose.
what can cause a vibration on high speeds when braking ? any ideas?
im suspecting a steering gear actually , but before i take it to the shop i wanted to see what others think.
thank you!
The 2014's switched to the same pads, and they don't complain about them as far as I have seen.

I like Akebono pads and believe that is what I have on my car. I swithed to Akebono pads on my C320 several sets ago and haven't looked back.

I thought they were exclusive to the E550, but now I don't know.




so they brand new...












Im guessing pads and rotors have nothing to do with my case.. as i only feel the SHIMMY in the steering wheel not the brake pedal.
im gonna take it to the shop next week.. but im thinking either the steering rack or control arms.. as i replaced them with not oem ones about 50k miles back.

My pad and rotor combo cured that.
Also look for debris on the inside part of the rotor. Another thing you want to avoid is throwing water at extremely hot rotors (is car wash or sudden puddle or rain). That will really mess up your breaking system.
Next inspect the rotor, and see if it looks shinier on some parts more than others. That would indicate a stuck or failing caliper, or that metal from the pad is stuck on the rotor.
If it got better when the new ones were installed, and then it got bad again, I am almost 100% sure its your brakes.

Perhaps if you've tracked the car to the point you're boiling fluid and near brake fire.. but in normal driving, nonsense.

i went today under the car to check tie rods - no play (was able to twist it by hand , not sure if its okay to be able to twist them by hand , since its got a ball joint (speaking of outer) but otherwise all solid , CAN SOMEONE CONFIRM THAT ITS OKAY FOR THEM to be manually twisted PLEASE????? THANKS)
control arms - all solid no play
all of the sway linkages and mounts - no play
inspected rotors and brakes - all smooth no grooves or anything obvious
also double checked and tightened wheel bearing , steering became a little stiffer but made no change to braking.
tires are still in a decent shape.
the only ONLY is the steering column makes a little clunking noise when car turned off and stationary (steering wheel left to right) right in the steering gear or linkage by it.
did balance my tires before i got the new rotors and brakes
and while driving straight its smooth as well.
very annoying , but will take it to a shop on monday.
thank you people.
