i have a stock master cylinder on my 78 camaro it does not have the break booster with it. i have replaced the calapers in the front and the wheel cylinders in the rear and bled and bled and bled looking for air in the line i can not find any air at all. i do not know if the car came with a booster or not so i went to the parts convient store (advanced) and asked for a mecanical master cylinder but the breaks are still very very spungy the rear drums are feeding off of the back tank and the front is feeding off of the front tank there is nothing between the tank and breaks but a splitter

do i need a prop valve or is there an aftermarket cylinder i can try

thanks for any help at all
