I am working on a 79 pace car with 2.3 turbo. Been sitting 15 years or better and it has no brake pedal. I replaced the master and that didn't do anything. Unable to get fluid to get out of the bleeders, and the are not plugged. I even applied vacuum and nothing. I did some reading and some people talk about the proportioning valve could be causing me the issue. I see some bleeder tool on line and its for GM valves. Any help here would be great!
