I have a 2003 Reg Focus Zetec 1.6 Petrol it's done about 1013k miles, I'm the second owner and purchased the car when it only had 11k miles on the clock so know it's complete history.
Can't fault the Focus I love the car and have only had 2 problems with it over the last 7 years that I've owned it.
Recently I've noticed that if there is moderate to heavy rain whilst I'm driving her that my hand brake warning light will be illuminated ever so slightly on the dashboard. After a few days with no rain the light will disappear again until next time it rains.
I've had the car down the garage to have the brake pads etc checked out and they are all fine and well within their lifespan, there are no problems that I can tell when breaking, she brakes as I would expect her to, doesn't pull or shake.
All I can think of is it is some form of electrical/damp problem?!
