After so many people moaning that my brake lights didnt seem to work I thought I had better do some investigation as the MOT is due on friday!

I knew they did work, but only if you pressed the pedal quite hard. But it does seem to require more pressure than I seem to recall. They passed SVA as they were - which I think equates to almost locking the front wheels before they came on....

At the time of building I put the switch in the rear brake line as recommended by a lot of people at the time.

Today I went out and bought another 3 way tee, a male-to-male adaptor and another switch. Fitted it directly to one of the front outputs on the sierra master cylinder. Brake lights now come on with much lighter pedal pressure - just as the pedal goes solid.

So there we are - fit your pressure switches to the front lines and save yourself the hassle of having to move it later!

or just fit an old fashoned mechanical switch where the pedal will hit it ('normally closed' type) - its got to be less hassle in the long run

With floor mounted pedals its very difficult to mount a switch somewhere out of the way....

It is actually a legal requirement that the brake lights are actuated with the front brakes.

I agree I had several atempts at a real switch before giving up and getting a pressure switch

I believe it can be easily done even on dmc congigurations.

Thinking of a small L shaped aluminium bracket behind the pedal near the clevis holding the switch or pressing the switch

Also DONT mount your switch with the terminals Upwards, ie with the fliud entry point at the bottom.
You can get a small air bubble in there that you cannot bleed out, and it makes your brake switch intermittent or non functional, even when the switch itself is in perfectly good order.

Fit the switch on its side or Treminals pointing downwards.

Yep mine is upside down

Having problems with the car pulling to the right on braking now, dont think its air, but wilwoods are a pain in the proverbial to bleed so it could well be!

Don't believe that, how come a lot of production cars have a mechanical switch operated by the pedal, the pedal does not now which is the front or rear brake!!!!!!!!!
