Remove it, it's useless in a seven as it works on a combination of front-end dive and vehicle deceleration to work. The valve will be calibrated
to the sierra suspension and weight distribution.
Just make sure the fronts still lock up before the rears else you'll be driving a death-trap.

Why do you want to remove it (since you must have had a reason for installing it in the first place).
What has changed, or what do you propose to do to compensate for its loss (assuming that it functioned as intended)

As above..
I fitted standard sierra MC, front disks and rear disks with no balance valve thing..
Passed the wicked test without any issues

My father thinks that it is causing the rear drums to drag as the car is quite difficult to push (out of gear)
We're on a mission to reduce rolling resistance (no jokes please worx, Pintos are the business) and he thinks its the bias valve

Jack it up. Turn wheels individually to find if there is excess drag in one. Also check front wheel toe which can cause drag.

(1) It isn't causing the drag unless you have fitted it sloping the wrong way. -- it is a "G" valve all that is inside is a ball
bearing that rolls up a slope under breaking.
(2) This type of valve isn't really suitable for your car.
(3) The brake drag is most likely caused by either the master cylinder piston not being fully released or mall adjustment of the handbrake & brake
self adjusters.
First ting to do is check the brake pedal has a return spring and is being pulled back fully.

Front wheel toe is setup correctly - done by a local trusted garage.
Brake pedal's ok. Personally I suspect the autoadjusters in the drums but we'll see
