    Hey all.
    I finally managed to sort out my ESP problem, man am i happy!!!

    Now my next issue..
    I get quite a lot of wobble on the steering wheel when i break at high speeds (any where from 40+).

    It feels like its coming from the passenger side front wheel.

    Any ideas?

    It will be a warped disc if thumping through the pedal and the steering:D

    They are cast iron, and the molecules in cast iron are always moving, one very hard stop can cause them to warp or go out of true.

    I had this problem on my V70R after a very hard stop, it was not there all the time and could come and go, once again the heat from a hard stop would either right it or make it worse

    Whilst this method does work, and we use it in the trade occasionally, I would not recommend that an owner takes to the road in their car with one flexy brake line clamped. The braking characteristics of the car will be greatly changed and a potentially dangerous situation could occur if you happened to require an emergency stop.

    Lol, i understand the objective, but also saw the potential hazard or the car dragging to one side or the ESP playing funny tricks.

    Could just as easily be, (more likely than a warped disc) worn ball joint, track rod end or bushes.

    The front control arm, front bush also causes this issue on a 203 when it perishes.
