Is the car 'B' rego (it probably should be with a hyd h/brake anyway) if so, throw the whole lot away (master cylinder & booster) and fit a twin master cylinder pedal box with balance bar. Than you'll have consistency with antilag on and infinite bias adjustability.

Group N rally car, we can't ditch the master cyl, or it'd have been shown the door at the beginning, itd also make my life a whole lot easier..
we're suspicious of it being a vacum problem, but it just seems a little odd..
theres no one way valve in the line form the manifold, checked this on two cars, <97 sti> so im guessing its either in the manifold or the booster itself..
as for race brakes, spoke to them yesterday...
