Thanks for your inputs, the MOT found no problems so the strut is probably OK, but I will take a look. I have wondered about the wheel bearing and the hub so I might try changing the wheel bearing. Recently the vibration can now be felt after a couple of miles and is worse when pulling up a hill, it feels like a one per rev vibration, but I have not found any significant heat when it has happened so I don't think it is caused by the brake. The vehicle is old but useful to have as a second car, especially this size for visits to the local dump etc. but I have zero confidence in using it for more than short trips.
