okay so recently the car has been shaking a bit on higher speeds at like 60 and up mph... last time one of my friends told me that my routers are gone... could that be it? because i think so too cuz last time that happend to my dad he took em to shucks and got them re leveled and it all went away, however if thats the case i'll just get those slotered ones but i want some advice from my fellers here..
thanks alot

and i wana get this the gold color with some slotered and drilled ones

want drilled rotors,they crack,brembo makes slotted and much higher quality than the ebay junk you posted.Don't play with brakes,drilled and slotted for 40 each means they are crap rotors.
check wheel balance.Never turn a mercedes rotor always replace when worn.

That's what the brake shop told me a while back... that they won't turn mercedes rotors... they only replace them.

What is the centerbore of the wheels you have? Are you tie rods and steering shock in good condition? Also, warped rotors will make it shake a bit but not that much. You should replace rotors every two pads changes. You can't turn mercedes rotors because they are too thin. I usually do a brake job every two years with all ATE parts.

tir roda are brand new stering shock is awsom never had any problems with that.... it doesnt shake masively but it does shake my hands soo.. i think it is the rotors cuz last time i took the wheels out my firned was like mann your rotors are gone... and i didnt know so i gues now i know

mercstar

HI, do you experience this only when you apply your brakes while driving at those speed? If yes, then your rotors are definitely suspect, but otherwise you should start your check with the wheel balance and move on to your other steering components.

Big wheels go out of balance easier than stock ones, and also do you have spacers on them? that can contribute to your problem too. Just my 2cents

berti_00

it shakes at higher speeds... and i just got new wheels and tires blaacned and everything brand new so unless they didnt balance them or something than i dont know....

but i am going to change the rotors soon soo well see

YNVDIZW124

What kind of lug bolts did you use conical or ball seat? do you have hub centric spacers?

berti_00

no spacers nothiing...

they look like this

did you get bigger rims albert? Maybe it's just your sig pic, but they look like they have a more aggressive offset and the tires look like rubber bands!

berti_00

yah i got brand new rims and new tires again this time they are 225's but same rims thoo just new again 9's all around... and it looks great.. but am beginging to think its my rotors gone too since god knows whent they were reppaced

Rotors won't cause shaking while driving, only while braking and only if they are really really warped, which its kinda hard to warp benz rotors, I have glazed my pads, and boiled my fluid and never warped them. They have a min spec thickness stamped on the hub of the rotor so you can measure them for thickness to see if you need new ones. Your problem is probably suspension rubber related, ie control arm bushings, or as simple as wheel balance. Tie rods would be if it pulls or jogs on the highway side to side cuz the ball joints fail, steering shock dampens bumps on turns, so can't be that either. If the steering wheel shakes, the problem is in the front end, if the seat shakes its a rear problem. I never run anything but bridgestone or michelin because they are the only ones that seem to make round tires....Also if your wheels are not made for benz and are lug-centric instead of hub centric that could be the problem too. Larger wheels=heavier which tend to be harder to balance, might try a different wheel shop for balancing?

technically you didnt do that to your rotors, Adam did ...

Quicksilver500

Yeah my buddy Adam drove my car 20 ish miles with the pbrake on and cooked my rear everything, the rotors were purple, flash rusted and even the paint was peeling.....idiot. But they werent warped!

True. Rotors wonīt cause shaking when not applying the brake. But they donīt need to be very warped to cause shaking while braking. And I cannot agree to Benz rotors being any harder to warp than others. Seen it happen far too often.
-Have your wheels rebalanced and inspect your steering linkage for wear.

i just re did the wheels and balanced them and what not so ones i take it on the free way well see... and also i checked the rotors and it looked like they were shaved quiet a bit cuz at the end of the round side its higher and on the actuall disk its deeper like 2cm or so

124-Fan

2cm is kind of impossible. Are you sure you donīt mean 2 mm ?
-It is normal for the rotors to leave a slight rim at the edge, since the brake pads donīt cause wear on the rotor all the way outwards. And 2 mm rim is still a bit.
I always grind the rim down to actual rotor thickness, so it is equally thick all the way out. If you know what I mean.. Still you must observe the minimal thickness stipulated by manufacturer... - Usually engraved on the rotor. And actual rotor thickness of worn rotors is not measured at the edge, because of the rim. Therefore you must grind the rim down to actual rotor thickness to see the actual thickness... or measure at the worn area inside the rim.
But like I said, bad rotors donīt cause vibration when not applying the brake.

hahah yah my bad its mm

124-Fan

Yep. Thatīs the metric system..

Cheers,

berti_00

i know am used to the european measurments and i always have hard time here with that kinda crap..

124-Fan

.. Itīs not crap, my friend.
You just have to understand it..

Cheers,

berti_00

thank you for all your thoughts sir... i did order a new set of rotors soo either way they are gone be replaced

Bigpete123

did you still have vibrations at freeway speeds after re-balancing your rims?
