Desleration sensative valve
 

Hi ALL
Anybody know what should be the angle of the above as the book states it should be the same angle as the donner car. I am afraid my donner car is well gone now. Secondly should this be in rear brake circuit.

Yes to rear break circuit.

I will have a trawl through my pictures to see if I have a picture of the item in situ, when I get in from work.:cool:

Cheers Ginge

didnt bother with it on mine. from memory i think it slopes up towards the front of the car

Phew
:o :D
I,m glad you said that Ash, cos I ain,t got the foggiest clue of what ya talkin about :eek: :D

cheers

I think its "Deceleration Sensitive Valve" Andy. Hope it makes sense now, must say though it took me a while.

Same as Ash mine didn't need it and yes it does slope forward.

I thought we were talking about the "pinto engine" :D

Cheers Spud....glad i now know I don,t need the gizmo ,:cool:

I didn`t fit mine either, but I did fit smaller rear wheel cylinders from an Escort, around 18mm bores instead of 20 ish ones from the Sierra.

I fitted one to my car, you can see it on page 4 of my build diary - www.deepfolly.co.uk. You should build it so it can be adjusted slightly, about 45 degrees pointing up towards the front should do it. The steeper the angle the more deceleration is required to activate it. It just makes sure that the rears don't lock first.

Cheers that looks brilliant, just one more question, is that in the rear brake circuit?

Hi Axle, hows your car coming along? Not seen you on here for ages. It is in the rear circuit, it limits the pressure to the rears under heavy breaking.
One really important point, the valve must go in the brake circuit after the pressure switch for the brake lights. If it is before the brake lights could turn off if you go really hard on the brakes as the valve will cut in and drop the pressure.
