Re: 1970 C60 brake concerns

Man I would be interested in seeing a photo as your truck sounds like it has had a similar life as mine I recently picked up (former fire truck turn utilitiy truck).

My thoughts are, and please confirm, if the master cylinder was replaced, is it still the single line unit? My feeling on those is you have to build up good pressure to the booster before the brakes actually engage, which is why the spongy feeling is there before the stop hits. Is it possible that it could be the wrong bore size?
