No brake fluid when bleeding

    Hey guys,

    I replaced and bench bled my master cylinder. I was bleeding all the wheels starting from pass rear and working my way to the front. When I got to the pass front no fluid came out...so I did a quick Google search and I found "possible bleeder valve clog" so I took the bleeder valve out and ran a wire through it. It didn't seem clogged but did what it said, put it back in and tried again, still no fluid. When I had the bleeder valve off I pumped the brakes to see if anything would come out, nothing did. So it leads me to believe I have a clog somewhere in the lines? Any suggestions? Thanks

    X2. Try cracking the steel line going into the brake hose and see if you get fluid out of it

    EDIT- By cracking, I mean loosening it

    Do you have front disc brakes? If so, you may have to depress the pin in the hold off valve. Its under the rubber boot on the combination valve. In 70 and prior year cars, the hold off valve is separate, near the master. The hold off valve restricts pressure to the front brakes until a set amount of pressure is developed in the rear. The idea is that front disc brakes act instantaneously, while rear drums have more clearance before they apply. The Chassis manual actually specifies this. I'm sure lots of guys are going to say they never do this, but why would the factory manual say it if there was no need.

    If you find the hose is collapsed internally, replace the other side too.

    Ok so I disconnected the steel line coming from the rubber brake hose to the drum no drip...I then disconnected the steel line from the MC to the rubber brake hose there's a drip so it leads me to believe the rubber brake hose is the culprit. I blew some compressed air thru it, nothing came out the other end so I just ordered 2 brand news ones I'll do the driver side while I'm at it and hopefully that fixes it, thanks for the help

    Probably is. The way I do it is to use the nut on the steel line as a bleeder. Have some one pump the pedal as if you were bleeding the brakes, but instead of opening the bleeder, you open the steel line going into the rubber hose. Btw, the rubber line doesnt get clogged, it collapses internally.

    Did you figure out how the hose comes off the bracket? Theres a little clip that holds it on the bracket. Probably buried under a layer of dirt and sand

    I ordered them yesterday I hope to put them in today, I'll let you know the status and yeah I found the clips, good thing because I stripped the nuts pretty good.

    Update: Installed the new rubber brake hoses. Fixed the side that was "broken" then went to the driver side to "fix" what "aint broken" well guess what snapped the steel brake line...:ball: Replaced the steel line from the proportioning valve with a brand new line then bled the brakes and fluid came out so I'm good. Now onto the starter issue...Thanks for all the responses everyone!

    well, at least the line wasnt that long! Was it rusty? Sometimes the line gets frozen in the nut and you wind up twisting the whole line into a barber pole instead of just the nut.
