    i drove it last night after i put new shows, and springs in the drums, replaced the drivers side brake cylinder, ive replaced the booster, i think i did the master cylinder, and i still have no rear brakes, and when i press the pedal slowly itll go way too far down, then if i have it in drive and press it slow itll go almost to the floor, then if i hold it there and put it neutral itll come back out a little bit..... What else should i try? Take to a brake shop and have them bleed it? Proportioning valve?

    are your rear brake shoes adjusted up so there is slight drag when turning by hand? /forums/images/graemlins/dunno.gif

    When it goes to the floor,,,can you pump it back up? hit the pedal a few times, does it come back up or does it stay down?

    ok i adjusted them so they are touching, but i figure since it is self adjusting that it would just take care of itself..

    did that help the pedal? They will self adjust when backing and braking enough to compensate for brake wear but not enough for un adjusted brakes.

    sometimes they are so far out of adjustment that it can cause your problem, its the next step anyway. after you adjust press on the brake pedal a few times and check adjustment again to make sure the shoes are seated before you let the jack down. good luck /forums/images/graemlins/thumb.gif

    do you know how much pressure should be released when the back brakes are bled? the pedal doesnt go to the floor. and it seems to just dribble out..... does that tell you anything?

    you should get a good steady stream, it tells me your brake shoes could be so far out of adjustment that the master cylinder cycles fully before the shoes finally contact the drum. also could be air trapped somewhere or the master cylinder not holding pressure. you gotta adjust the rear brakes as your next step.

    you can bleed it just like a wheel cylinder just use the brake line fitting to let the air out, sometimes air will get trapped at the fittings.

    if the brakes were to far out one of the pushers (?) on the ends of the wheel cylinders may have popped out. check them and nake sure your not getting air in there.

    dude.....the condition you are describing is a typical master cylinder failure but I assumed you already replaced it!! adjust your rear brakes and replace the master cylinder if it wont create any pressure. /forums/images/graemlins/dunno.gif
