Default Vibration under braking at speed . - 03-12-2007 , 12:30 AM






w124 230TE 1991 ....

I have a vibration that feels like a warped brake disc ..
however it is not ’felt’ through the steering wheel nor the brake
pedal .
The faster you are travelling the heavier the vibration .
Is there any other possible explanation other than a warped disc ...
bushes or anything else ??

I would guess that the vibration area is left & rear .

Wheels and tires out of balance.

Another possibility is worn suspension bushings... On your car it would be
the lower control arm bushing/ball joint... so buy a whole new unit.

In my case it was a bulge in a tire.

I had a severe shuddering when braking from speed on my 1987 300E when I
first bought it in 1999. It assumed it was warped brake discs as that
was exactly what it felt like.

I replaced the worn our tires with new Michelins and it has never
shuddered when braking since. It rode smoothly so I don't suspect tire
balance, separation bulge, or flat spot was the cause.
