can anyone tell me where i might be able to get one of these as it is a non serviceable item and ford no longer have them, it is situated near the passenger side rear wheel up near th chassis a brake pipe comes from the front goes into this valve then comes out the other side from what i can understand it reduces the brake pressure to the rear wheels, has anyone had this problem and is there an easy solution i.e an aftermarket set up that fits straight on any help would be much appreciated, its for a 3dr by the way but is the same on a saph cossie.
