Just trying to sort my brakes out properly and I've found this bit that needs plugging into the rear circuit somewhere. I've forgotton
it's name, but I know it's used to stop the back wheels locking. I hearby declare it named a brake thingy.
Anyway, does anyone know which way round it should go?
Does the master cylinder go at A and the slaves at B or is it t'other way round?
Does it need to be mounted in any particular orientation? It would fit best horizontally...
Cheers Lads.

its a decel valve,opinion is it wont work on a 7,if you do need a valve(some do,some dont)use an adjustabubble one from a fiat uno
If you are using drums on the back and discs on the front, you will not need it.

It relies on the front of the car dipping under braking to move the ball bearing in it to the front to reduce pressure.
A Locost doesn't wollow about like a large Sierra.

Genius!
That'll explain why it rattles too.
Question answered and still time to go to the pub! 
Thanks!

hence the mounting angle is also important. as said, stuff it and follow the crowd, uno bias valves are in commom use.

Guys,
One more time - BIN IT!!
Please do not use this valve. Its not suitable for 7-type vehicles. Plus, you need to establish the necessary decel level, and this requires
considerable instrumentation, decel sensors, suitable data logger, and weeks of test work.
For those of an iquiring mind, here's the theory of how this valve works - allegedly!!

ive put one on my car - i have discs all round - if you guys all suggest binning it, whats the best alternative?

Alot of people use fiat uno adjustable ones. Search for a thread on them as im not sure what unos they come off.
Ive used a wilwood adjustable one, picked it up second hand so wasnt that expensive.
I'm coming up to having to work out my master cylinder sizes and getting some. I've got discs all round but have a balance bar in the pedal
and will be able to choose whatever master cylinder sizes will be correct (once I work out how). Is it still a good idea to have a decel valve in the
rear circuit with this kind of setup?
Cheers

Kind of defeats the object of having a bias pedal box and setting it up.
Blimey, didn't mean to start an argument!
Said item has been binned now. I'm going to try it without for now and see how it looks once it's running. (One day)
Fit a Fiat valve it is simpler to set up.
The Girling G valve isn't that hard to set no harder than anyother brake presure regulating system (try setting up the Teves load sensing valve
Chrysler UK used in the 70s) BUT it isn't SVA friendly the Fiat Uno one is and its cheap.
If you do a search you will post showing the bracket and adjustment mech you will also find some stuff I wrote up on who to get the correct setting
-- do the road testing this carefully starting from a front bias.
For safety Front brakes should always lock first in all conditions.
