1 Answer

the proportioning valve simply puts the foot pressure on the rear and front in a correct proportion...as you know at least 65-70 of the weight gets shifted to the front, so proportionally has to put the braking forces where they belong....spongey tells me something is wrong with the fluid...has tiny air bubbles...on a microscopic level making the fluid cloudy? perhaps you used new-old-stock...?
