Wanted - Brake Pressure Reducing Valve

[Matthew]

It seems there's no good way out of this - either I have to pick a random pressure reducer and hope that the balance is good enough, or rely on a valve from the donor which was designed for a completely different weight of car.

I've got an MOT station within 1/2 mile of my house so once I get that far I can see myself taking a quick trip over there (on a trailer of course) and getting them to let me know what the balance actually is.

At least that way I'll have some hope of getting through
