It's not just for the handbrake. Do your brakes work as normal? Can be a warning that your break fluid is too low.

Ahh wait, you might have hit the nail on the head there - fluid is ok but my rear brake pads are getting really low, would they have some sort of sensor on there?

cold weather sometimes makes sensor in brake fluid reservoir play up.

I will second that mine illuminates for a few minutes in cold weather then goes out once engine bay is warm

Most likely low fluid. Try opening brake fluid container and closing it again, this seems to work as a temporary measure!!!?

Could well be the cold weather, or low fluid, or possibly a combination of both.

My brake light has been on and off for a few months. Tends to come on in the morning if it's cold, but if it's been a warmish day, doesn't come on in the evening. Fluid is around 2/3 full and pads all round still have plenty on them. You need to make sure there's enough fluid to cover the white float thing.

Put it down to 'just one of those things' - after checking you have fluid and pads, obviously......
If there's anything out of the ordinary, best to keep an eye on things.

It may be the sender in the fluid resovoir sticking. Mine done it on my old MY94 and I know of other that have done it.
The solution is to take the top of the resovoir and give the sender/float a poke i.e push it down and up a few times.

My '93 WRX was doing exactly the same.

Changed the pads and topped up the fluid, it's fine now

Do as Scott says. Most common cause. The sender gets a little sticky on the older cars. Give it a poke and watch it bob about a bit then check the light.

add a little more fluid. has worked everytime for me. (i'm on my 5th impreza)

stockcar

the reason NOT to add fluid is simply because this also works as your "low pad warning" indicator!! if the system is full of fluid with new discs/pads then as the components wear the fluid will gradually approach the min. level, when it brings the light on....................

wouls suggest you check/ replace pads or discs (as suggested above) and/or also check the 'float'...........................

I had a similar problem a couple of years ago on my 93 wrx. It turned out to be the actual cap for the brake resevoir. The rubber insert had expanded and was pushing the sensor down V quick fix, just push the insert back in properlly, hasnt done it since

Exactly what Alyn says It is a "feature" As the pads get low the piston (s) go further out, therefore there is less fluid in the wee tank, and presto, (!) light on.

New pads will see the pistons further in, and the light go away And yep - it could be the float, but almost always it is the level dropping as the pistons extend.
