Hydraulic brake light switch.
I am running a twin master cylinder with bias bar set up.
Does the switch want to go in the back line or front for the best operating presure ?
Having done a search some say back others say front.
cheers

In the back as it fitted in with the rest of the wiring.

Hi mate
Just my personal opinion but i would have to say in the front line due to the higher pressure but that's not from experience so we will have to
see what others say.

Front as it's a bias box. Basically there will always be more pressure in the front line. If you put it in the rear line then under very light
braking it may not even come on depending on what pressure it's set at. I'm sure someone on her had problems with it in the rear
before
If it looks wrong it probably is wrong.

Front. And you can use a banjo bolt switch which makes
the installation really nice!

To be 100% legal it should be the front --- largely forgotten part of the old road traffic acts.

Hi.
As Wyn has ^^^ said the banjo bolt switches are very good. As for the other more common type if you use one from the range of older MG's etc
they will work fine in both the front and also in the rear of the rear brake line they work with light pressure. Also there is a 4 way T piece from
that range of cars which makes mounting the switch easier than breaking into a line elsewhere. ( Is it possible to have a 4 way T piece. You know
what i mean  )
Unlike some of the racers who fit the ones that need very high pressure to work but can be made to work to pass a scrutineer by standing on the brake
pedal. Mind you they tend to change them when other drivers keep running up the back off them .
Cheers Matt

Ive fitted t piece type switch in rear line and it doesnt work well. Probs better in front. Ive since learnt that there are different pressure
switches available. Apparently series 2 land rovers use the lower pressure switch (only know about land rovers as my mate repairs them).

Hi
Slightly off topic but is it no longer permissable to have a microswitch activated by the motion of the brake pedal?
Regards Mick

I'll let you know as it's the way I've done it Mick.
Sva before the end of the year I hope.
If it looks wrong it probably is wrong.

Standard way of operating the brake lights since the 1970s I would advise using an automotive brake light switch rather than a standard
microswitch.
You can also get pulll operated brake light switches
