Having now sorted my oil light problem I now need to decide what to do with my front rotors.
I have found a source for new bobbins but I seem to recall reading that the rotor mounts on the ST4s are aluminium ?
If this is the case then I wonder whether it will be the mounts that have worn and not the bobbins giving me the excess run-out that I have.
The discs themselves are still well within tolerance for thickness after 48,000 Mls and I dont have any pulsing problem to worry about after a recent good cleaning sesssion but I have been pre-warned that they wont pass the next MOT Test so I will need to do something.
I dont want to spend money on a whole set bobbins only to find they are unable to sort the problem.
Anybody done this fix ?
