Ideas required!
Just found out that the handbrake is not hitting the warning switch. Dont know why I didnt notice before but I guess thats life!
Anyway, its a bar steward to get at but I need to rectify the problem. Anyone got any inspirational ideas? Pulling the car apart to get at it isnt an
option! Only thing I can think of is super glueing a small pad on top of the switch, (It only needs 2-3mm), but I'd need to do it at SVA while
its on the ramp! 
If its broke, fix it. If it aint broke, take it apart and find out how it works!

Dont fully understand your set up. Do you mean the warning light ( brake ) is always on because the hand brale, when down, does not hit the switch
or is it a type that hits the switch to tun the warning light on when you lift it.
do you have a test switch on the brake fluid res - cant remember the sva requirments

can you adjust your handbrake right off so you have to pull the leaver that much further?

If your master cyl has a test button on it you've no problems. If not then put in a switch into the hand brake line. I.e. remove or bra eak into
your existing cable and fit a switch to the cylinder end then run a wire from the switch to earth and Bob's your uncle. I think the switch may
have to be marked or labeled though not quite sure.
If it looks wrong it probably is wrong.

Sorry guys, should have been a little more specific.
The switch is on the handbrake, sierra donor.
Basically the light is on all the time as when off, the handbrake handle is not contacting the switch, ie it wont go down far enough to break the
switch contact. I need to put a little pad onto the top of the switch so that the handle makes contact. Unless others have better ideas? 
If its broke, fix it. If it aint broke, take it apart and find out how it works!

just to recap; the switch is of the type that wen you press on it, contact is broken - i.e. when the hadbrake is off so the lever is down, the lever
does not press on the switch hence the light remains on?
basiacally the solution is to somehow get the lever to press down on. this can be done by:
1. lowering handbrake positions
2. raising siwtch position
3. extending switch (wot you propose)
4. extending handbrake lever
seeing as 1. and 2. would need dismantling which you say it not possible, you are left with 3 and 4.
without seeing hwat you have, it is not possible to say which is easier.
I would guess 3. is easier by glueing on a small tube onto the switch - usually that uave a tound pipn sticking up.

Yup! What you said!
Non of it will be easy due to time constraints. Dont know why I didnt pick up on it before, guess I was pre-occupied with other stuff.
I'll make some bits and pieces up and take em with me on tuesday. Hopefully SVA man will let me sort it on the ramp.
If its broke, fix it. If it aint broke, take it apart and find out how it works!

Why can't you do it how I said then?? I puzzled Unless you don't want another hole in the dash or something??

No test switch on MC's. Not sure what you mean by putting a switch into the handbrake line? Have got a micro switch mounted under the handbrake,
(standard sierra item), but somewhere along the line the handle has stopped making contact with the switch when in the off position.

Use the wire that goes to the handbrake micro switch find it somewhere convienient cut it and the end that goes to the hand brake make safe and
isolate for later. The other end is the one you need to take to a switch and then to earth. As I said it'll probably need some sort of
identification though perhaps someone else will confirm this.

OR you have an earth short on the cable to the switch. As it is only earthed when the handle is down. Lift the handle a fraction and it should break
the earth contact, therefore you probably have an earth fault on the cable to the switch. If the switch is not positioned correctly then you would in
most likely hood NOT get an Earth at any time.
Check you wiring first.

Sierra switch is switched to earth, so when the handles down the switch is broken, (push to break).
Wiring is ok as Ive had the dash apart and checked it, and when I push the switch the light goes off

The switch in the handbrake, from a legal/SVA perspective is just a convenient way to test the brake fluid low warning light's bulb.
So for the test all you need to do is remove the wire from either the switch and the other end and fit a test button somewhere convenient.

can you take the handle off and modify it slightly?

That would be the easiest way to modify it but it means taking the car apart and I just dont have anymore time!

Just get a random switch/button, and wire it across the m/c level switch with a pair of scotchlocks.
Once it's passed SVA, take it off and throw the scotchlocks in a fire, horrible things

IIRC the switch is adjustable by slackening the fixing screw and moving the switch up/down I thought you also had to have a sender on the master
cylinder as well for the SVA.

You want the simplest solution
You don't want to strip it
You don't have many options
they are
Strip it and sort it
OR
as a few have said myself included
PUT IN A SWITCH
It really is that simple even simpler if you do it as per Martyn_16v's instructions.
But you WILL still have to cut the cable to, OR remove the terminal from, the handbrake switch or it will still have an earth and the light will stay
on.

So I guess you don't need indication that handbrake is on ?

correct. Not needed for SVA.]

Just as an extra, if lowering the handbrake presses the switch to extinguish the warning light, then there could be a possibility the switch
isn't working.
