    Brake bleeding

    I've replaced my master cylinder and booster,bled with a vacuum bleeder. Pedal still soft. So I decided to gravity bleed.  How long should that take? Starting with furthest rear, taking a long time to get fluid out!.  I did bench bleed the master. New lines from master to distribution block. 68 with front disc rear drum.

    thanks

    Open all the bleeders at the same time,make sure you keep refilling the master,don't let the level get below 1/2 ...may take 2-3 hours + ...jj

    Great flow from fronts.  I get some fluid from rears,but not a flow like front. Do I have a problem?or is that the way it  comes out of rear when gravity bleeding?

    Mark,  the new lines you mention, there is not a bend in them such that the line goes back "up-hill" is there?  If yes, you could be getting air trapped there.
    Good Luck

    Re: Brake bleeding

    Is the brake light ON on the dash?  If so, the differential pressure valve may be tripped and needs to be recentered.

    Brake light is not on. I think the stupid adjustable proportional valve to the rear is a problem.

    Re: Brake bleeding

    Which brand prop valve do you have?  I quit carrying one of them because of issues like yours.

    It's many years old. I had gotten it from SSBC in a conversion kit.

    Re: Brake bleeding

    Now that you have flow ,close all the bleeders and pump bleed each one seperately...do rears first...jj
