Ive bled my brake lines on my 79 Z and all that work are my rear drum brakes. I have to burry the brake pedal when I stop and it sucks!! I replaced the master cylinder about a month ago. I also replaced my front calipers about a year ago. I have pressure in the lines because I was able to bleed them all... including the bleeds on the master cylinder. Whats up with my brakes?? Is it the booster that might be bad? Thanks!

 

ok... I make a post to get help... not get ignored. Ive helped people on this forum and I'd like a little help here in return. Is there anyone that might have had this same situation with their brakes and could offer some advise of any kind? Thanks.
