I've never heard of it done. I know when the brakes were properly adjusted I could virtually stand the van on it's nose [:0], took quite a shove though. Not sure how these remote servo's work can you give some details [?]
correction, will has one, dave has a larger bore master cylinder. they are a exceedingly good thing to fit.
panky a remote one works the same way as an integral one, uses inlet vacuum to pull a diaphram and multipy the hydraulic pressure about 3x, also lessens the pedal effort. plus you can fit it anywhere.
