Hello all,
I have been a lurker of the forum for quite a while but not posted for a while. I have an early E55 (99, S) and the brakes have recently developed a judder. You can hear it, feel it through the car and also feel the pedal hitting back.
The symptons are very much like warped discs so this weekend I replaced the front discs and pads. £500 lighter and the problem is still there.
When changing them I did notice the nearside one to catch the dust guard (I must have leant on it) very slightly. BUT it didn't rub on the disc all the way round, just at one point like a buckled bicycle wheel. This was with the new disc fitted and I cleaned the hub well with an abrasive pad prior to fitting so that it was flat. The buckle is very very slight but seems to be the route of my issues.
Anyone know what could be causing this? I am going to remove the disc once again to make doubly sure that the hub face doesn't have some corrosion or similar that is making the disc not sit flush. However before I do are there any known problems with the hubs? The bearings are not making any noise and the car has not had any accidents to cause this.
Any help would be very much appreciated.
