Have bias braking on my Escort mk2 I have purchased and unable to get on with it, would like to replace it with a sevo.Due to lack of space in the engine bay have read that the sevo can be fitted behind the glove box?
Is your problem with the weight of the brakes, or the balance? A servo would make the pedal lighter, but you mention brake bias which makes me wonder whether you are trying to solve a balance problem.
