Help!!!!!

[jprcrpr94]

I've got an 85 4Runner. I just got done putting on IFS calipers, FJ80 rotors, 2nd gen v6 m/c and booster (used), and extended lines. I bled the brakes and get a solid pedal with the motor off. While it's running, however, I have no pedal!:eeek: I'm thinking it might be the used booster. I was planning on wheeling this thing this weekend, and this is the last thing I need to do!! Any thoughts!?

Bleed it more. Are your rear brakes adjusted properly?

They're adjusted. I'm pretty sure I got all the air out. Would it have a solid pedal when it isn't running with air in the lines still?

Try a new master cylinder...as long as you're confident you've bled it enough.

Does 'no pedal' mean the pedal goes all the way to the floor with little resistance?

When it's doing this, is there pressure in the brake lines? Jack up one front tire and spin it with the motor off and again with the motor running. You might just have the booster-to-master rod too long.
