Hi Phil,
I haven't had a chance to check the brake system though I'm more and more convinced it's an electrical issue but seemingly effecting the right side of the car. My right brake light flashes on and off intermittently (confirmed by someone driving behind me) and the driver's side electric window occasionally has a mind of it's own and just goes up and down randomly. I should also add that it's not just the ABS light coming on the actual system engages too.
Would that all make sense that somehow it was all down one side?
