    Ok after swaping the ft and rear axles putting
    SS brake lines no brakes. I have manual bleed the system no luck. I put my snap-on Vacula brake bleeder and ran about 1 gall
    of fluid still very little brakes. Replaced the master cylinder
    still no luck. Tapped on the porprtion valve no luck ayone have any ideas on how to get a good pedal??

    Thanks,
    Bo

    Chris,
    Yes I bench bleed the master. The pedal goes almost to the floor I have a little brakes about 1 inch from floor.

    Did you bleed in the correct order? Farthest to closest to the master cylinder?

    man do I feel your pain!

    Is the brake light on on your dash?? if yes- its the combo/prop valve...what I ended up having to do- was undo the lines on the valve..just left them connected - un screwed them etc..and pumped the brakes, that was enough fluid/pressure to get the flap in the valve back over to where it belongs.

    I gravity bled- till the fluid was pouring out of my bleeders, I manually bled till my leg was on FIRE....I vacume bled till the vacume pump caused a kink in my hand......it wasnt until I did this with the valve- AFTER hitting it to get the air out, that I got my pedal back......

    as an FYI- some vacume bleeders recommend (instructions say) to start CLOSEST to the master cylinder, not farthest away..

    good luck.....mine still arent the best- but my new calipers are sitting on my rear seat, waiting for the snow to leave again, so I can get them on- and bleed the front.
