today i flushed the brake fluid in my 94z (fluid looke like used oil). everything went good till the front passenger caliper. it stoped sucking fluid, i used mityvac. well while it had vacuum and with the bleed screw loose i pumped the brakes thinking it had some trash in there blocking it and i could push it through. came back around and there was no vacuum and i assume it sucked alot of air in the system. now i cant pull fluid through it only air. i been pumping the mityvac for like an hour trying to get fluid and i only get a little bit with mostly air. anyway i can fix this faster or do i need to just keep pumping. i figured after an hour it wasnt going to work.

what can i do?

On a car that old, the brake hose could be collapsing.

same thing a friend of mine told me last night. ill get them replaced. there is no way to really check is there? cause its the inner linner that collapses right?

Yep. In recent years this seems to be more common than it used to be. Sometimes they will literally form a one way valve when they collapse allowing fluid to go only one direction.

i replaced the hose and still nothing. im getting more fluid but still mostly air...
