fill up yer brake fluid.  RTFM.

Hi all

Over the last couple of weeks, when starting the car from cold and releasing
the handbrake, the handbrake light will stay lit for roughly 30 seconds or
so.  It will also light when applying the brakes.  Both of these situations
seems to pass after about 5 minutes.  The light will only illuminate when
you press harder on the brake until, eventually, it will will only light
when you actually use the handbrake.

This seems to have started since the damp mornings over here in the UK.  I'm
thinking maybe it's a sensor which is drying off as I drive?

Any suggestions??

Thanks

Julian
