Handbrake warning light appearing?

[nick_karkie]

My friend owns a TT auto J-spec and he says his handbrake warning light comes up for 10 secs after he floors it from 40-80 say. It doesnt happen every time he floors it but quite frequently.
Anyone know what is causing it? auto box fluid?
thanks

Top up the brake fluid.

Yes, I know it's above the "full" line already, but top it up anyway :D

Is it as simple as that Ian? honestly, will that solve his problem and stop him worrying about nothing?

thanks

Yep. It's caught a lot of us out in the past. The light is the low brake fluid warning and when it's everso slightly down, usually caused by pad wear (the caliper pistons go further and so more fluid out of the reservoir is used), then high-G manoeuvres cause the fluid to dip just below the sensor, triggering the light.

How long will a bottle of open brake fluid keep for? I got some of the toyota, stuff last time my light came on, about 8 months ago. will this still be ok?

I know it doesn't cost a lot, but silly to buy somemore when there's some in the garage.

<Official line> Nope. Once opened you should use it straight away. <Official line>

Depends really on how much you hoon about really. If your pushing the system every day then you really need to have top grade brake fluid. If Miss Daisy would ask you to put your foot down a little, you'd prbably be OK.

Personally for the sakes of what? £10 max, I would get some fresh.
