First off, its the master cylinder, not booster. Sorry, i cant change the title

Im piecing together a 5lug power disc brake conversion kit for my 1963 2wd GMC but for right now im still running around in the truck with the stock drum brake system. Problem is, i have to pump the brakes several times before i even get any brake pedal feel. I know older manual systems you will have to pump the brake pedal a little, but this is very excessive. Im thinking that the diaphram is worn out. Also just thinking about rebuilding it instead of buying a new one from LMC since i just need a temperary fix What do you guys think it could be?
