sorry for the odd question. i was wondering if there is an audi non abs master cylinder that is a direct bolt on for a mk2 booster. i was hoping to get a master with a larger piston diameter. a few i ve seen are from the 90,91 audi quattro coupe 20v piston diameter is 25.4mm. i would love to have this kind of clamping force. so anyone have any idea if this will bolt up to the mk2 booster. any thoughts or ideas are very much appreciated... thanks all!
