i have a 1987 3 door cosworth with a leaking brake pressure control valve.

ford are no longer available.

will this fit and be high quality due to being compbrake?

thanks

NO, this is a residual pressure valve in the link, not what you need, or want on a road car.
All these do is let most of the pressure out back down the pipes after you have applied the brakes, but not all, it keeps a very small amount there to minimise brake pedal travel etc.
The valve you want is it near the rear wheels like a cylinder, not uncommon for these to leak, any rear disc equiped sierra one should be ok.

As tabs says - why not ask anyone here breaking a saff 2wd or 3dr - keep it original that way???

ive got the same prob,got one of here from a breaking saff,that now leaks so im going to fit an adj bias valve.

mr_intex

it seems that fitting an adjustable bias valve is the way to go!

who would recommend one?

what brand of valve?

will it be hard to fit or does it just drop in where you take the old off?

thanks

There's no magic formula to these valves, I have used Wilwood adjusty ones in the past, but these were inside the car(escort), just a case of plumbing it in, once set will not need any further adjustment, some extend the pipes and have the valves inside the car, but a bit more work of course.
I would have a look around the breakers, at Fords see what other ones use a similar valve that have rear discs, especially newer models as may be able to order/use these, saves hassle.
If you do end up fitting a bias valve, make sure you set it up in the wet.
