brake reducing valve question
Hello,
After looking by some posts there are some thing not cleair to me. One my car I have ventilated discs at the front, 8” drums at the rear and servo
with master cilinder all from an 2,0i Sierra.
Also i’ve got the Brake deceleration valve from the Sierra on my car. And want to replace it for an Brake Reducing valve from an Fiesta or Mondeo.
Which one is the best to suite al locost type of car?
This new Brake reducing valve wil not be screwed in to the mastercilinder but on the place where the Sierra valve was fitted (at the back of the car).
There for it must fitted horizontal and not vertical like the Fiesta. Somewhere on this forum I read that fitted it vertical it helps bleeding, but
effects it the functioning off the valve?

I'd agree with zxrlocost.
Try without first. The 8" drumbrakes on the back should give you a good system that doesn't need a reducing valve.
If you do use a valve the physical orientation of the valve body doesn't matter so long as it's not the Sierra G-Valve.
The G-Valve function relies on the valve body orientation. The other types rely on differential orifice/piston area and springs.

Yes first try just joining the pipes at the existing reducer -- just either a puka joining union or a "Tee" with a bleed nipple used to
block the unwanted outlet.

Sounds to me like your "brake deceleration valve" is known as a metering valve, and your "reducing valve" is a proportioning
valve. They are 2 different valves with 2 different jobs. Both are required for good braking on a disc/drum system.

Easier than me typing it  .
