My Dad just bought (privately) a 2003 is200 automatic about 2 weeks ago. 51000 miles on the clock and had a brand new MOT before he bought it and new discs and pads. He has noticed that a couple of times when on the motorway, possibly after a bit of braking his steering wheel starts to judder like mad and he has had to grip it hard to stop it from going everywhere, then after about 10 seconds of doing that it is ok again, its only done it about 4 times. Is this the brake calipers everyone keeps talking about on here? sounds expensive to get fixed. Feel a bit bad because I was the one who told him to get a Lexus as they are bullet proof! now this happens straight away!
