Working on a project truck I bought that I'm about ready to shoot, but regardless running into something I've never dealt with before. Brakes are good and than maybe every 3rd-4th time you use them they start out normal and than get real soft. Not acting like there's air in them. Person before me had just replaced the master cylinder and not seeing any leaks. Flipping bleeders are rusted up, so I'm working on that but again it's not acting like a normal air in the line where it's just soft. Sorry about no paragraphs, my enter key isn't working on here for some reason. Thanks
