Hydraulic Brake Light Switch
Hi,
trying to find a cheap M10 switch (and brake line 'T' piece).
Doesn't seem to be any suitable on the bay - I may be wording my search incorrectly - but have found one for £12 on Europa site, is this
reasonable?
Cheers
Ray

I and another two members have the hydraulic ones and each one of us has had problems in that the lights do not come on until the brakes have nearly
locked up, we have all now fitted alternative switches onto the pedal, make sure you get a really low pressure switch, the amount of coming togethers
weve nearly had wasn't pleasant
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

one thing to watch is mounting it so you don' t get a bubble between T-piece and switch. A lot of people have them pointing their terminals
upwards which can cause problems with them only coming on when brakes are given a good shove.
There are, at least, two pressure versions high and low. You want low.

Mechanical Brake Switch
Why don´t you use a mechanical Switch?
That way you can push the pedal a couple of mm before you actually have braking pressure.
This means light comes on earlier.
This is not a new idea by any means, this has been discussed before.
Beware of what you wish.. for it may come true....

So how do you identify a low pressure switch?
(i think i've got one and my plan was to mount it at 90 degrees to vertical so i didn't get a bubble)

I have also heard it helps if you put your cds in the freezer overnight, ignoring hydrostatic effects hydraulic pressure is the same at any point
in closed hydraulic system where no fluid is actually flowing.

? Not sure what your point is?
We are talking about switches that switch at different actuation pressures, not looking for the best place in a pipe to put the switch...

I mounted my hydraulic switch right on the master cylinder, as the Tilton system has two possible places for the lines to go. My lights go on right
away, and I've had no problems with the switch (my leak is further down the line).

I think you are well aware of the point I was making.
