I have a 2003 focus st170 and now and againthe hand brake light will flicker on and of.Can anyone shed some light on what the problem is. Thanks

 

Low fluid/pads are low. There's a sensor on the reservoir, as the pads wear if the fluids a little low it will bring it on. If you've plenty of meat on the pads just top up the reservoir to the line. Can always dropper some out when you fit some more when the time comes

 

The pads where changed bout 5 months ago but I recently handa new hand brake cable fitted would that affect the light? Ill check reservoir and c how it looks.What is the correct fluid to put in?

 

It will just be low fluid now the pads have worn a little. Think it's dot 4 but double check in your manual.
Check your cylinder isn't leaking too above your clutch pedal. It's a common problem, you'll have a wet carpet behind the pedal. Sure the 2 systems are linked iirc.

 

Got it sorted it was just low fluid I have a stainless steel cover over the resoviour and cannt c the level without taking the lid of.I was told to put dot 5.1 in and he said it just has a higher boiling point and I read the bottle and it said it can be mixed with dot 3 or dotv4 so I put some in and prob sorted . Thanks for the advice people
